User blog comment:Livin' in a fun house/Phineas and Isabella possible kiss in Candace Disconnected/@comment-961279-20110613143402

I think you're making too much out of this snippet. From what I see, it's accidental physical contact when their noses touch, which Isabella is naturally happy to have happen. But there hasn't been enough character development for Phineas to get to the point where he might turn that accidental contact into deliberate contact with a kiss. This may happen later on, since we're seeing different instance where Phineas does care for Isabella, but so far that's just as a friend and not affection for Isabella specifically.
