Why did PB come to Finn's house in burnning low?

i dont know what is really going o happen but this is my theory I think PB wants finn to stay away from FP that's why she go to Finn and Jake's treefort to keep an eye on Finn that's my theory...

So she could win his corazón back

I believe she wants to mostrar her true feelings but I think she also is going to tell Finn something about flame princess that will make him stop dating her

the first: 'cause she was collecting some taxes
the second: 'cause she wanted finn to stay away from FP

DUH COLLECTING TAXES
