I think fans would be angry if Carlie was killed because so far she's the only character close to Peter and who knows who he is that even remotely thinks there is something wrong with him. Take that character away and we're right back to square one sort to speak. So it's not so much liking Carlie, as much as it is she being the one to expose Otto.
thats exactly why i expect her to die. Allyn Gibson
is right though, as i don't know anyone who actually likes that character.
