User blog comment:Livin' in a fun house/Phineas and Isabella possible kiss in Candace Disconnected/@comment-5151799-20110613145120

No, I think you're taking it much too seriously. The guy just teleported in front of her and Isabella made a smile, as she usually does towards Phineas. So... no kiss.

And there will likely be no kiss in AtSD either, since most of it will take place in the alternate dimension, which Isabella is presumed to not go into as she has not been in it in any of the film's promos and such.
