For once Rodimus isn't thinking about heroics, or his pending coolness, or even weighing how much he wants to tell Arcee where she can shove her orders versus actually following them...he's too preoccupied with Orion. That and the freshly inflicted wound on his shoulder. Orion and his shockingly...well, ruthless attacks. Even expecting a tough fight (it is OPTIMUS PRIME they're fighting after all) Rodimus wasn't expecting this. THIS Optimus doesn't seem to have any interest in holding back, not for their sake nor even his own. Orion's initial blow had came down hard on Rodimus, slicing deeply and painfully into his shoulder joint; the plating there might as well have been nothing. He can't tell how bad the damage is just yet, but it's leaking energon like a spigot and he's not getting much use out of it. Even with Magnus' fortuitous arrival, Orion's attack on both Autobots is relentless. Rodimus is only barely fending off the blows, and he knows his plating wasn't built to take the kind of punishment their estranged leader is doling out either. At this point it is needless to say he's only getting in Ultra Magnus' way. He needs to get out of this fight, and fast.

Rodimus can hear Arcee and although she sounds a million miles a way, he uses her voice as a goal to try and move toward...if nothing else, in between defending himself from Orion's vicious blows, Rodimus uses his good arm to concentrate fire in the places Arcee seems to be aiming.
