You don't consider spending the entire comic with SarahTedd lying on the floor with Grace crouched over her, to be OT3 fuel??

Yes, I believe Sarah could cause fake-Box to appear and carry on a conversation - and fake-Box would say something Sarah would plausibly guess Box might say.
No necessary, or even non-coincidental, connection to what real Box would actually say.

Here's a though:
Can Sarah say: "Box, show yourself".
And if Box was watching at the moment Sarah casted spell, can then Sarah talk with fake Box?

To expand on the above post, when an individual moves, it is the product of a mixture of involuntary, automated, and voluntary processes. The involuntary accounts for necessary functions, such as breathing. The voluntary usually covers intention, and clarification through decisions along the way. The automated is the meat of the matter, we do not think ourselves through each step, we simply walk. Automaticity, or the formation of subconscious response patterns, is one of the most important aspects of human cognition. Without it, we could not easily walk, read or speak... let alone run, write or sing. However, it is most easily disrupted by bringing voluntary thought to bear on the task, a prime example being an attempt to remember a number that you regularly input "by heart".
I figure there are a two probable explanations for Grace's behaviour in Sarah's simulation.
1. Sarah's spell is using her own automatic patterns and subconscious, in conjunction with her understanding of Grace's personality, to synthesize an "actor" which responds to her requests. In this case, Grace could use any automatic patterns, like speaking, that Sarah has established. If her instructions go outside the personality or the bounds of her own patterns, the spell will either fail or derive a placeholder.
2. Sarah's spell is using her own memories to synthesize a sensory composite which reflects her direction. In this case, the composite would only be limited by Sarah's memories and capacity to distort them, and would thus be particularly susceptible to projection.
The first option is both more interesting and more useful for simulation. The second is just what people do normally, we don't need magic for that.

 
She behaved how Sarah's subconscious expected her to behave around Tedd, and may have been an over-exaggeration, which essentially proves that the spell didn't carry over what might have been going through Grace's mind at the moment of the spell cast. So that would also apply to anything that might have been loaded into memory on a computer. Sarah's interaction with Grace here is not any different from her interaction with vamp!Sarah and wolf!Sarah, it's basically all inner monologue.

You know, this spell actually does fit Sarah pretty well, in retrospect.
 
Looking at her character across the whole of EGS, her role has largely been to be the perhaps the most normal person in a group of people who are, to be honest, weird, and gaining power at an alarming rate in-universe (albeit years out of universe). The observer to their weirdness, the Jane to their Tarzan.
 
This ability kind of expands on the same lines as her character: she has phenomenal cosmic power, but mostly to cogitate and reflect upon what those around her are doing.
 
She dreamed of being a wizard once... And she will continue dreaming of being a wizard. Only better dreaming...
 
Come to think of it, would a mind-entering power allow someone to see all this? Pandora could maybe piggy back in Sarah's mind as she did with Grace and have a looksie. I now start to realize that she may have been making a bit of a lie when she was saying 'I must find a way to observe what you do in there'.

More experimentation is required.

So The Matrix was what Highlander II should have been? 
 
Also, if it's a contest, there should be a note with the number written on it somewhere nearby (unless the person running it memorized the number), Sarah could just find the note.
 

Hmm, you know, there haven't actually been anything that shows that she can't use other people's abilities (rather than just imagining them). Last comic had her question why she didn't see herself glowing, but she wasn't using any spells in the simulation, so of course she wouldn't glow, and this comic she didn't even try to use Tedd's mark. This feels like a red herring, Dan is trying to make us think that she can't simulate abilities, without actually showing it.

I've paid attention to the borders of the comics ever since Dan started doing stuff like this.
He really needs to make it easier to distinguish, though.

Pandora, you and I are on exactly the same wavelength.  You just expressed what happens all too often in EGS - a lot of talk about fun stuff that *could* happen, followed by all the reasons why it shouldn't happen.  Thank you, Rhoda, for taking us in a much more interesting direction.  I think you and Ashley have much in common. 

Yes. the question now is full scale nudity or shrunk nudity.  Either way is good, but I have a fully validated pervert card, YMMV

Is Rhoda's loose cannon canon?

Yes.
No. Also, the Catgirl-ageddon itself would be extremely hard to justify (although Dan would try very hard).
Technically true and I shouldn't complain, because I'm similarly nitpicking sometimes.
On the other hand, my hypothesis that Pandora marked several hundred people (in Moperville) already seems to be shoot down, and with how big deal she was making it with Sarah, the probability of someone else in similar situation is very low.
... why just girls? If we are going this route, EVERYONE in the mall can be shrunk ... and transformed to catgirl ...
Yes. I hope it won't happen off-panel too.
(What. The probability it happens is already 1, question is only if we will see it.)
Agree ; they are already in changing room ; Rhoda can bring one - wait. They will probably insist on packing it, it's not likely they let Catalina through paying with the scarf on.

GIRL, BUY A SCARF FOR YOUR EARS AND STUFF YOUR TAIL UP YOUR SWEATER!
 
When fictating becomes loud enough to startle your dog....

Seeing all of the girls at the Mall getting shrunk would be quite a sight...although the current scene has high probability of seeing tiny Catalina getting cuddled by Rhoda, which should prove to be adorable.

Is it too much to hope for that Rhoda's spell gets tangled in Catalina's magic and we get a Shrinkageddon instead of a Catgirl-ageddon?
Ah... as far as we know. Hypothetically, other exceptions may exist. Please forgive me for being a bit obsessive about details like this but they nag at me at times. >.<

Oh c'mon girls, don't go into the changing rooms! People aren't permitted inside there with food, and hijinks just aren't the same without the popcorn!

Well, one Danish sports champion is named Tom Bogs, whose last name is pronounced exactly like that. He was a multiple European champion in... boxing.
I am not even kidding.

I know of a powerful enchanter. He is able to create fire and explosions where he points at, and fire bursts of fireballs very rapidly from his staff.
 
There are some who call him... Tim.

Was he there, too?

It could be a lot worse. That genius Didio from DC named one of the archvillains of the execrable series Countdown... Bob.
Yes. Bob. I am sadly not kidding.

So, Pandora cops out and gives an alias that will take Sarah and friends much longer to figure out.
I do like the expression the second panel--it shows her playful side. The three illustrations of her names do well at showing what she thinks of each name--Pandora is the trickster, Chaos the "beast", and Raven is herself as mate to Blaike and mother to Adrian.
Also, paranoia points in the last panel for Sarah being worried that the Immortal in question might be watching and get offended.

Hey, if Sarah does her job well, she might be finished in time for her date with Sam next Saturday. Remember Sam?

And this pretty much conclusively identifies who made Dex's amulet with the jar emblem instead of a box, doesn't it?
