Seasons 3 and 4 I'd keep pretty much the same. It's only Season 5 I'd change. I know some people think that Cole was unforgivable によって the time he'd become the Source, but I disagree. It wasn't as if he'd done that deliberately - he'd tried fighting it.

I'd start off the same way. Cole returning from the Wasteland, trying to win Phoebe back because he still loves her, her unable to accept him because she doesn't trust the effect she has on him. That's realistic. Then he'd back off, try to just prove he can be a good person. Try to just be a friend/ally if he can't be her lover. Maybe I'd still...

Phoebe: "I'm making スープ for Cole, he'll eat it in a bowl. I guess that's my new role, just making スープ for Cole."

Cole: Uh, Phoebe?
Phoebe: Cole! What are あなた doing here?
Cole: Well, I got a call from one of the tenants saying that, uh,
Wonder Woman was terrorising the landlord.

Cole: I'm a one woman demon.
