Bulk had noticed. The first time he could dismiss it. Sad as he was to see him go, after they'd only had so much to actually catch up after the imposter Makeshift. Going back to the stars to find more of the Wreckers, or any other Autobot refugees, was a pretty legit reason for leaving. If it meant more Autobots to help, all the better. Primus knows they could've used all the help they could get.

But the second time he'd started to suspect something was up. That he was avoiding them for a reason. Even after everyone but Ratchet(even if he did try later) chimed in, trying to get him to stay with the team. But he wasn't sure why. He was on the same planet now, they could call him for help on missions. But no matter how many times it was tried, he never took the invite to come back to base.

He shifts some where he sits, and sends send Boulder off to hang out or play with You. Something in the way Wheeljack said it, he got the feeling maybe their partners shouldn't hear. Once his partner is settled in actually trying to have fun, wow why did he wind up with such a serious partner. He tilts his head toward Wheeljack, looking curious of what he wanted to talk about the Team.

"Sure, what about the Team?"
