In a way, the tail is kind of nice; it's been a long time since Leo had a full body hug like this. Not just while he's been here, in this weird place, but even back home. He'd been fighting with Raph for so long... It feels so stupid, now.

He knows this isn't Donnie's usual place, and he does feel a little bad, putting him in this position. Even though Leo really, really needed it. Especially now that he knows there's some cosmic force laughing at his misfortune. His head's still buzzing with a dark cloud of pain and despair, even though he feels like he can breathe again, with Donnie holding on.

Once he calms down enough to use his voice again, he croaks out a soft, "'M sorry. For how I reacted when I first saw you." He snakes an arm around Donnie back, finally. "This place messes with our heads sometimes. I... thought what I was seeing wasn't real."

He squeezes.

"It's gonna be okay, though. I'm not leaving you either."
