So Bubblegum wants to go to bed with Marcy after realising that letting Finn go was a mistake? I really hope this doesn't mean she'll be thinking of Finn when she's with Marcy, because that would just be unfair to the latter.
The fact that the world "isn't ready" is exactly why we need something like this. If this pairing became canon, a lot of kids and even parents might wake up and realize that there's nothing weird about same-sex couples.
"i don't think the worlds is ready for a lesbian copele in a cartoon for kids." If it's not ready now, when will it be ready? It's not like people are going to get less homophobic while the media is perpetuating negative stereotypes and Christian parents wave their Bibles around.
