[The whole thing is giving Arthur a bit of a headache--having an extra person's thoughts in his mind is chaotic and confusing, and he has to take a moment to sort out what Will is saying from what he's feeling.

To say nothing of the fact that he's still holding onto Will's wrist, which he's suddenly very aware of and flushing hot, but there's so much weight here. So much Arthur hadn't seen under what had apparently been a facade, blinded by his own affection.

But then Will is looking at him with something just a bit timid, and Arthur realizes he doesn't know--apparently, it's a one-way street.]

You're not--it's me. I'm not sure what's happening, but as soon as I touched you, I could...hear you.

[There's a beat, then he feels himself go pink and quickly lets go.] I'm sorry. I shouldn't have intruded--I didn't mean to.
