FUCKING. OW.
He would not handle that well I don’t think, no. Having lost Cyndia was incredibly traumatic, and it’s something that has left him scarred (and scared). He’d probably be shaking while he held Seto’s hand and would try to make sure he had everything about Seto memorized, down to every little detail, even how he cleared his throat and how his nostrils flared just so when he breathed… Because he knows it might be the last time he sees any of it.
He’d try to hold all those fears in, because Seto is already sick and he doesn’t need to hear any of that blubbering mess. But he’d break down once there was a door between them. He wouldn’t be able to sleep. In the end, when Seto finally gets well, Pegasus will probably fall ill because of his poor self-care and stress. The irony of this is not lost on him.
Good to know. I was thinking pretty much the same thing.
