[Even though Leo has also wondered about different timelines, it still hurts to think that this Donnie might end up in a different time branch from him. He'll love and protect any Donnie in any timeline, of course, but to lose the brother he had with him here... It just hurts to think about.

(Assuming he can even get back.)

Hearing how paranoid Donnie has been hurts, too. He knew about the nightmares, knew Donnie had anxiety as he was healing from his concussion, but to know the fear hasn't gone away is another thorn in Leo's heart.

Which is maybe why he's being so overprotective. Letting all those thorns sink in and hold him hostage.]

...I wasn't trying to... to take your chance away from you. I mean, I wasn't even thinking about it like that. I'm not mad about what happened in the past, or, well, not mad at you. I don't need you to fix it, I just need you to be alright. I... needed to be sure.

And... [He scuffs his foot on the concrete. This is embarrassing to admit, but maybe he owes it to Donnie now.] ...maybe I... felt a little jealous, too. If you could get something out of that guy that I couldn't... [He grimaces.] Well, then you kinda don't need me as the face-man anymore, right?

[Leo has always needed his brothers; he wants to be needed by them just as much.]
