Five frowns, and suddenly wishes he'd been drinking less. This is important to know. Some piece of information Wrath wouldn't have given if they hadn't forced him to drop a clue that Five couldn't help but poke at. Wrath could have refused to explain, but he still tried his best to answer as much as the curse would allow him to. Either because he's polite, and even Five can admit that this is what friends do. Or it could be because Five is a smart guy, and he should reasonably be able to provide some useful insight into the matter.

So drinking was a mistake, but he works around it to give him the attention it deserves.

He thinks about the anguish inside him that he ignores. No one but Wrath even notices, and so it could be the same for him. Wrath's curse could be causing him excruciating, unending pain, and he doubts he would have said one word about it if he was given the choice.

"You were hoping to learn from them, and it ended up the other way around? Or is bringing someone back from the dead key to breaking it?" He doesn't know if he can answer that, but Five theorizes anyway. "I've done it, you know. I've brought my siblings back three times now. Some things you can only fix through time travel."

So in theory... if that's the answer, Five could do it. Only at the cost of everything, but it's not like he hasn't been that desperate before. It's what he's still planning, after all.
