I might even answer a few if I don't get asked them after work

Tim! 1, 37, 53

Tim 1: That he's not scared. Most of the time he's just being brave and lying to himself that he's braver than he actually feels (at least the Tim I play who hasn't lost everything just yet.)

Tim 37: I can't really think of a secret Tim wouldn't share with a partner. I don't think he's big on hiding things - he's more an unreliable narrator. So, he'd admit his truth, but he wouldn't really lie

Tim 53: It was Sasha. Since learning what happened to her? I don't think there is anyone he can fully trust anymore. There will always be that question in the back of his mind if this person is a shape shifter
