I'm at 10% worried HW is gonna fall in love with Fionna or something. I hope it will be a similar situation to back in the day where /co/ would always spam Fern was gonna steal Finn's girl and then Fern died horribly and Finn is still (kind of) with HW.

I'm more worried that Side Quests is gonna suck ass and also sad that the AT movie very well may never be made (despite being announced last year Muto mentioned somewhere that it hasn't actually started production yet and they're still looking for someone to fund it).
