He has the face of a devil, sharp and beautiful and just a little bit evil, and Diego should really know better when Klaus gets that clever look in his eye.

Diego has never sucked a cock before, he decides that needs to change

As soon Klaus realize he can make Ben solid again, Ben start to wonder about some of the experiences he never got to have alive.

The first thing Ben does when they land is punch Klaus. The second thing he does is hug him.

Klaus, he reads, fingers shaking along the edge of the page of his sister's book, was a very eccentric child. He could also see ghosts. This, he thinks, is very spot on. (Klaus outs himself on live television when he’s fourteen, and the past never really goes away. Publicity's a bitch.)

“This isn’t going to work,” Diego said, once everyone had stopped moaning on the grass and/or throwing up.

Vanya was never the only one that felt lonely and uncared for in this family. Klaus has some things to say before she tries to bring this world to an end. And hey, maybe those things will convince her not to.

“Why would you do that?” Vanya asks. “After what I did to you-” “There’s not that many people who can understand how it feels to be raised by Reginald Hargreeves, you know,” Klaus contributes. “If you’re gone too, who are we going to tell our trauma to? A therapist? Ha. Hard pass.” “But I-” Vanya starts to protest, but then Allison’s arms are slung around her shoulders, and she buries her face in her hair, and for a second Ben lets himself hope everything will be alright in the end. (Once again, the Umbrella Academy saves the day - not that the day cares much about it one way or another.)

They’d been back in time for less than a month when their father forced Klaus back into the mausoleum. But maybe this time his family can do the right thing.

“So,” Klaus announced and clapped his hands together, “What’s the plan, team? Champagne and confetti? Shots? How are we celebrating the not-end of the world?” “We’re thirteen, dipshit,” Diego responded, and then took a moment to process that for himself. “Fuck.” Number Five looked like he wanted to say something along the lines of “Now you know how I feel”, but he was man enough not to. Klaus applauded him in his head. He wouldn’t have had the restraint. - Or, the Hargreeves siblings after the apocalypse.

Kenny's mom assuming that Diego and Klaus were A) a couple and B) Number 5's parents was both bemusing and amusing at the time. But that was because it was the only time it had ever happened. Now though? Now they just can't understand why these misunderstandings keep happening.
