...Oh for crying out loud Phineas!!!Isabella has a crush on you, no not a crush, she'swith you!!!The reason she spends almost every day of the week with you and Ferb is because she just wants to be with you. She often daydreams of you in Phineasland. She dreams of marrying you when you're grown up. She even keeps a shrine head-statue of you made out of your used gum.How'd you think she feels when you two were alone together in Paris, the City of Love?, that's what. She tried to get your attention and spend time with you alone, but you were too focused on rebuilding that plane of yours. But after seeing you having a mental breakdown when you and the group were stuck on that deserted island, she realized that it wasn't the amazing, confident kid she had fallen in love with. When she meant by "the Phineas Flynn that she fell into this situation with", what she really meant was "the Phineas Flynn that she fell in".You're a smart kid Phin, but you're just so darn oblivious to how Izzy feel for you.
