Pavel was just laying the coordinates into the navicomputer when Optimus Prime stepped out of the turbolift.
"An' what exactly do ye think yer doin'?" It demanded in Scotty's voice.
He closed his eyes, counted to three, and opened them again. Nope. Still there, and still looking at him in a very angry way.
"...Um?" Kirk demanded, staring at the Transformer from his Captain's chair.
"Donae 'um' me, lad, that's my girlfriend he's sittin' on!" Optimus exclaimed, stomping over to wear Pavel was sitting in his seat, struck dumb.
"Captain, it might be advisable to take counteractive measures at this time," Spock informed him calmly.
"In this situation, Commander, you don't need to wait for my permis-"
At that moment, Optimus reached out, grabbed Pavel and threw him across the bridge. The last thing he heard was "An' keep yer filthy hands off my lady's unmentionables!"
Then he woke up.
"Are you okay?" Hikaru asked from his seat across the shuttle's aisle. "You were kind of twitching."
"My brain scares me sometimes," Pavel admitted, and refused to say any more about it.
