you are your own worst enemy, know your enemy;
[ blunt impact she can do! faith hasn't had a good rush of pure adrenaline and let her survival instincts take over in this way since the last time she'd really fought angel. of course then, she'd actually hoped to lose.
this time, though, she's not watching her back and trying to navigate the weird as hell social cues of a hundred other women in blue jumpsuits. this time, her problem is right in front of her and she can punch it. or, grapple, as seems to be happening now that angel's succeeded in driving her to the ground. pound for pound, angel's just as strong as faith, and a lot smarter.
but, all her life, she's been underestimated. if we were being ridiculous, we might say she can smell underestimation a mile away. the thing is, she used to be really angry about that. and now, she's seeing it from angel too. which isn't upsetting -- he's got her back and that's really all that matters. in fact, she's got this really weird clear sense of acceptance about it. it works for her.
she doesn't snark back at him; faith's never really been good at that part (that's more the good slayer's thing, anyway). she grunts, angry that she's lost out this round of struggling and tries to force them closer to a wall so she can get any modicum of leverage, hoping that angel will assume she's just trying to futilely wriggle away. ]
