It'll be abundantly clear to Luka that after the first like three punches, Garrot stops playing around. The first few punches impact against squishy fat and inactive muscle, but once he gets going the Princess will probably notice Garrot taking tiny little breaths out as each punch connects. As each fist connects, it'll hit tensed muscles; is fightmaster Garrot bracing himself?! Yes, absolutely, but he'd never admit it.

"Definitely." Garrot can't really stop himself as a proud little chuckle radiates from his entire body. "I'm pretty sure you've done this before." Sure, that's an exaggeration, but Luka clearly needs encouragement and support right now. And speaking of support...

"Wanna talk about what's got you so angry?" He'll close the distance a bit, and put one giant hand on the Princess's shoulder. "I doubt that was all about me being alone."
