"I-I... wh-what?! N-No! I-I--! You--! D-Damnit, Sonic!!" Finally giving in to the urge to flail, sort of. There's just this little huffy shift of his arms before he crosses them, sharply, and stomps his foot a little bit, frowning, deeply, and blushing hotly all the way to his ear tips as he looks away, grumping.
