For a moment Bucky feels a pitch of vertigo and the all consuming panic that he's back overseas. Because it's not like he never had hallucinations of Steve brought on by various factors, and sometimes those hallucinations warped and shifted from what he remembered, making him more or less sick, depressed or happy, or--

But the feel of Penny's nose against his hand grounds him, and forces him to look more closely at this very odd reality.

"Steve, you-- how the hell did you bulk out that much? Did you start taking something while I was away?"

Surely this had to have happened slowly over the time he was overseas, some new skin treatment for the scars or steroids to bulk his muscles? But even that makes no sense, it's just his mind desperately grafting towards something that might make some sort of sense.
