Sentinel genuinely isn't sure how he feels about this. Disgust, mostly. Mechs like Megatron can't change and to think he's genuinely being spared is laughable. No doubt Megatron is keeping his distance because of being in Autobot territory (this is Autobot territory, right?) and because killing someone who can't move isn't much fun. Sentinel knows this from experience.

He can't speak, but breaks optic contact. That's a big bunch of horseshit.
