Five got stuck in a subway station of timelines with Lila. Consciously they were there 7 years making them fall Inlove with each other . But now they found a way back home.

The family all got reunited and since Lila and Diego were married, she chose Diego over him. He was sad but, they didn't know they were gone for 7 years so he just hid it.

You stepped in the house and sat beside Klaus who was practically all dirty, but since the Hargreeves's are your friends you didn't mind it.
