Isabella
The show is geared towards a younger audience, and Phineas and Isabella are only kids. They will never marry each other.
Yes she DOES!
He did not have kids, nor did he marry.
It is going to be Mishti (his childhood sweetheart) that Baljeet is going to marry.
probably around the 2020's.
A lot of people hope Phineas. though Candace makes a reference that Isabella might marry Ferb. though it says Ferb's in some kind of camp when he grows up. so I want to say Phineas, though I might be wrong.
Ummm... I don't think that there's a very good chance of Phineas and Ferb getting hitched. According to the episode "Quantum Boogaloo", Isabella will probably get married to either Phineas or Ferb.
Yes he does. He married Vanessa but vanessa also have a crush on Johnny her classmate.
He could marry Isabella, since in Phineas and Ferb's quantim boogaloo the Future Candace doesn't know who Doofenschmirtz is, meaning Ferb doesn't marry Vanessa.
In the episode "Phineas and Ferb's Quantum Boogaloo", when Candace's child refers to Isabella as "Aunt Isabella", Isabella exclaims that this means she will marry Phineas. Then, Candace points out that she could also marry Ferb. So basically, Isabella probably marries one of the two brothers, but which one is still unannounced.
Of Course She Will Marry Phineas. Because In the Episode ''Phineas and Ferb's Quantum Boogaloo'', It was said by Amanda, the daughter of the future Candace, that Isabella looks like her Aunt Isabella. So Isabella thought that is was going to be Phineas because of the fact that she doesn't have a crush on Ferb but was stunned when future Candace said that it could be Ferb. But I think it will be Phineas that Isabella is going to marry because of Ferb having a crush on Vanessa, Dr. Heinz and Charlene Doofenshmirtz's daughter. But also Vanessa has a crush on her classmate, Johnny. So the story is all mixed up and I really don't know what happened.
Gene wanted to see Phineas instead of other people because he valued their friendship and enjoyed their time together. Gene found comfort and companionship in Phineas, which made their bond special and important to him.
