Percy never would have imagined attacking someone.  Actually it seemed that such imaginations were at the furthest reaches of his mind.  There were certainly some exceptions to that generality, but he couldn't foresee taking a cheap shot.  Maybe in defense of himself or others, but...the thought made him exceptionally nervous.

This was not good.  In fact, it bordered on terrifying for Percy Dervish.  The humpbacked witch had it out for them...and her disposition had likely been affected from being treated like a horse earlier...

Percy dashed down the hallway and narrowly missed a toppling chunk of ceiling.  Percy dove around the corner in the nick of time.  He quickly whirled around to check on Erin.

It may have been terrifying for Dervish, but Erin was having the time of his life. He was built like a seeker anyways, whip-cord thin, something that came in handy for Quidditch and now, for running. He skidded around the corner just in front of another blasting spell, ducking the same chunk of ceiling as Percy and then twisting around to check behind him. Looked like the statue couldn't actually follow them - at least, it wasn't now. Colored stars and smoke, coupled with bit of plaster and stone, were still causing a cacophony of light and sound in the corridor beyond.  Some green smoke drifted out into their new hallway of choice and Erin waved it away, then ran a hand through his hair to dislodge stray bits of stone and dust and whatever else had been stirred up by the attack. He was still grinning.

"Brillant, Dervish," he said happily. "Good idea, that. Top notch, full marks, etc."

Percy was relieved to see that the debris had not crushed Erin.  In fact, the pair had escaped unscathed it seemed.  Percy was huffing, collapsed against the outside hallway wall.  Percy's arms were thrown over his knees as he bowed his head and tried to compose himself.

Finally looking back to Erin, who seemed...genuinely thrilled...Percy's expression contorted with bewilderment.  This guy was really out of his mind.

"I'm uh....glad you enjoyed yourself.  As well as us both being in one-"

Another blast came crashing through the wall by Percy's head.  Percy yelped and lept to his feet.  In the heat of the moment, Percy was trying everything he could think of to stop the statue...to return it to normal.  But all the adrenaline was clouding his mind and he couldn't focus properly.

"Stop that thing!"

Percy couldn't think straight.  He just began spouting off random words now.

"Stoppicus Maximus!  Shootius Stoppum!  Be Niceius Pronto!"

Had he really just tried those?  Wow.  Paintings began screaming as they passed and the humpbacked witch statue came crashing down the hallway after the duo.

"AHHHH!"

Erin beamed down at Dervish, who was bent nearly double and panting with exertion. Dervish looked up at him apparent confusion... Erin's grin grew wider, almost manic. Turn-about was fair play, and if Dervish felt confused now, it was only payback for earlier when he'd been befuddling Erin beyond belief.

Percy began to speak, but he didn't get time to finish his no-doubt very earnest and rule-abiding comment about how at least the both of them were safe before the stone above both their heads exploded. It was enough to wipe the grin off Erin's face at least momentarily as he ducked and spun around on his heels, blue eyes wide in incomprehension. Amid the bits of falling stone the witch's cackle rang out, and then Erin twigged that she'd come for round 2 and began to run. He grabbed at Dervish's arm as he went, the stupid twat yelling nonsense words at the statue after them as though it would stop it. Ravenclaws were supposed to be smart, weren't they?

Finite Incantatem drifted leisurely through Erin's mind, at counterpoint to the swift rush of adrenaline powering his pounding feet, but he didn't call it out. They were racing down the hallway in a cacophony of screams from horrified paintings, the heavy stone thudding and scraping of a previously-inanimate witch at their heels and spells bouncing off the walls around them - why would Erin try to stop it? He hadn't had this much fun all week!
