[That headbutt, an all too familiar form of reasoning, shakes Leo's expression. He even loses his balance for a second, but he does not cry out. That felt very real. It may not have been Elliot's intention to prove he was real, but Leo no longer has any doubt. This person isn't some ghostly apparition or a trick of his mind, but is genuinely Elliot.

Leo rubs his forehead. His stunned expression breaks to a weak smile, but it is hard for even Leo to fake "okay" right now.]

So you remember. You think that I, too...

[It hurts, because Leo knows he was very close to doing something absolutely stupid. He was dangerously close to acting like Jack. If not for Oz, Leo would not be able to face Elliot right now.

But because of Oz, Leo is able to turn his gaze confidently to Elliot. There's a lot that he wants to say and a lot he should explain, but thanks to Oz he is able to start out honestly. And without initiating a fight to the undeath with his best friend.]

I'm alright. Oz beat me up before I did anything stupid. [...] I'm sorry, Elliot.
