If Kevin felt any embarrassment after his demonstration/performance, it certainly didn't seem to show as he quietly complied with Vlad's instructions. "To the gym, huh? I hope you've got something heavy enough to actually strain me this time. Say, an M1 Abrams, or something." he joked as he followed the lead of the guards. He wasn't sure if he truly was ready to lift an entire tank, but his point was true enough. His enhancements had made gym sessions pretty dull. Maybe Vlad had something more challenging in mind this time. 

He pricked his ears up as he heard Beelze talk to Limbo. Kevin had reason to be quite interested in the both of them.
