I-I didn't-- I didn't think of that. Why did he give me a hoodie? Why didn't he give me a single sock or something? Do-- do you think there's something wrong with this? Was it naive of me to think this could all work out? [He pulls the hoodie off over his head, so now he's just wearing his weird mask shirt.] Th-this was a bad idea... the thread must have been poisoned or the red must be the blood of my family or - or something... I'm gonna die...

[oh but right the fainting thing. after staring in horror at his hoodie for a couple seconds longer he snaps to attention and realizes hershel's health is more important than his dumb bullshit]

O-Oh. But - um - that's - that's good? I'm glad you're not... like, dead, or anything. [he pauses.] You and Clive and Heiji are all friends, right?
