Heh, on the upside, Vanilla's looking to make a massive comeback with the new elements of his origins being introduced. Always felt like that was one of the reasons Marceline kinda has a habit of overshadowing other characters sometimes. She and Ice King easily have the most gripping back stories of any character to date (both as individuals and especially together).
PB and Finn we know relatively little about in comparison, so it's much easier to get invested in the aforementioned two as a result (at least, in my perspective it is). Hopefully the upcoming season does something about that.
THATS WHAT HAPPENED?! I thought you were just put marceline in a attractive outfit then had finn replicate what lsp saw in gotcha and were being pervy and made pb look in her panties coz she... was wet? I'm sorry this may make me sound like a perv but I'm just telling you my previous view on this.
Oh, I knew he was top naked... I thought that he was trying to gain her sexual attraction... and I thought PB was making sure she could do the same O_O so yeah I was pretty disturbed and alarmed as to where this picture was going. ...I'm not sure if it's more or less alarming that Marceline actually STOLE their clothes. xD But it's funnier.
