It's easy to avoid speaking with Optimus after the fight - their newly restored leader doesn't, frankly, seem to want to speak with anyone...a request that Rodimus is more than happy to oblige. In fact, he would probably continue to oblige if not for the fact that he's stuck in the medibay with him.

Ratchet was quick in making repairs, but with so many of them injured, so few supplies and only one of him, there's only so much he can do at a time. The more major of Rodimus' wounds have been sealed up and the structural damange to his chassis at least stabilised but the welds are still fresh, and sore. He hasn't been able to do all that much in the way of moving about, which is for the best anyhow since he's exhausted. Despite this, he's hardly spent a minute offline, instead choosing to spend his time miserably stewing in his own guilt, waiting for Optimus to awaken.

Rodimus is sitting on the edge of a nearby berth when he notices Optimus stir, finally showing signs of life after passing out cycles before. He's been waiting for this moment, knowing that eventually they'd have to talk, but now that the moment's come, Rodimus suddenly wishes he were anyhere BUT here. What's he supposed to say?

"...hey. You're awake. Um. How do you...how do you feel?"
