Edit: It occurred to me that I got their relationship backwards. I'm leaving it though, as I can't remember a panel that would fit with Diane instead of Susan.

This is still what Grace's stance makes me think of:

 
I'm not really sure this one is mine. I might have downloaded it because I liked it:

 
Thinking out loud is a bad habit:

 
This was a follow-up to one (that someone else made) where Rhoda had just run away from Justin using "pointing power" on Noah:

 
Again, I'm not sure this is mine:

 
He's a sweetie after all:

 
I don't remember exactly what inspired this one. Someone had mentioned Mr. Verres's "disco days":

 
I don't really like this one either, but for completion's sake:

And that's it.

Tedd's probably a girl. And I guess Elliot learned to notice the (apparently subtle) difference in his voice.

Nope, she already checked on him and subsequently left to figure out Magic's plan for Tedd.

Since everything was lost from the old server, I'll re-post what I had made too. I'm not sure these are all of them, but it's all I found.
This was my first one:

 
Poor Abe:

 
One of the many slays people made of this comic:

 
Raven has bad luck with doctors:

 
My really feeble attempt at the glue thing:

 
Fringe family:

 
Watch where you point:

 
Someone commented "Thin Elliot is thin" on this one:

I'll make a separate post for others...

She is worried for him. He has made a lot of experiments that have either been shaped by or entirely relied on the intense magical field in Moperville. (Also, as an aside: I suspect Tedd can only use his Marked spell because of the magical field, but I am uncertain of how much of a factor that plays in Grace's concerns.)
In short, once the field is gone, much of Tedd's work will have been rendered irrelevant. This is probably also why Tedd is reluctant to believe Box. It's a massive shock to his worldview, especially if Box is speaking the truth. Note that he is arguing with himself in order to convince himself that reducing the magic field is actually a good thing.
