It's all just falling to pieces again. He'll try to come up with some plan to fix this, and it will only make things inescapably worse. And that he felt the need to call Billy at all means he can't just turn back the clock to a time when none of this would have mattered to him. It's too late.]

[He manages to look slightly offended at the question. Dignity, he has some shreds of it left, doesn't he? Hands scrabbling for purchase on the tree bark, he begins to climb unsteadily to his feet. Exhausted, sick, and disoriented, he still manages to get himself mostly upright before he stops, face pressed against the bark, and just breathes for a bit.]

You're...actually here, aren't you? I called you. You're actually here. [He reaches out (blindly, ha) with one hand, searching through the air for Billy.] This is happening. You're-- [Sucks in a quick breath.] You're looking at me. Not anyone else.

[Not dying hallucinations. He's not falling across an event horizon.]
