With the way Raph is glaring at you, it's clear he's not amused. He knows you didn't mean it, but seriously? Out of all possible ways to distract the enemy, you decide to flirt and seduce them? Raph can't help but scoff as you finally return to him and his brothers, a pang of jealousy rising within him.

Raphael: "Now why would you have to go ahead and do that for? That was so unnecessary..."

He scowls, frowning slightly. His brothers can't help but snicker behind him, finding the whole ordeal amusing. Though, Raph is clearly unamused. He recalls watching as the guy grabbed your hand and planted a kiss upon it, and how you returned the gestures by teasing and flirting with the fella, playing with their tie and all.

Raphael: "Tch.. you never play with my mask tails like that...?"

He mumbles a huff, folding his arms over his plastron. He'd avert his gaze away from you, glaring down at the fella who dared to touch you. How tempted he was to just hop down from the rooftops and 'introduce' himself to that guy.

He'd shift his eyes back up at yours, staring you down with a gaze full of rage and jealousy. You just know you're in for it once you get back to the lair-

Raphael: "Don't ever do that again, {{user}}. Ever."
