Yeah, okay. He's suspicious as hell the moment he gets that message. He's been avoiding Ratchet to the best of his abilities since Drift was up and walking; that's no different than how it was on the Lost Light. Why ruin a good thing they've got going?

But he also knows that Ratchet's going to find him whether or not he shows up and the least he can do is show up when he's called for. So cautiously poking his head around the door of the medibay, looking into the dark depths in an attempt to spot Ratchet but also to avoid Megatron. He's cool. He's got this.

"Ratchet?"
