As the fighting progressed, Lee was learning one thing - he was not as ready for the fight as he first thought he'd been. It was one thing to say that he would focus on the defensive spells, but it was a completely different thing once in the middle of battle, to focus on healing, as well as protecting himself from the offensive spells aimed at him. He couldn't keep up with everything he needed to, eventually dragging an injured comrade behind a desk in order to perform Episkey on a few gashes, telling himself that if he at least stopped the bleeding and helped mend their broken fingers, they'd be alright to get away without needing someone to go with them. Seeing a Death Eater heading in their general direction, Lee quickly re-aimed his wand at them, sending them flying backwards, and hopefully making them forget about his location.
Once the person he was tending to was up, Lee watched them head back into battle, which he couldn't understand, but he didn't have long to question their actions, as the desk he had been hiding behind was blown aside, and Lee had to run in the opposite direction to protect himself, shooting a body-bind spell over his shoulder.
Stopping dead in his tracks, Lee saw a flash of green light out the corner of his eye, and he couldn't help but look, needing to know if it was one of their own. He was stunned to see George crouching over a body, and Lee was sure that was the only place the light could've come from. "Fuck..." He muttered under his breath, and suddenly, his chest felt tight, but it wasn't by a spell. He couldn't believe what he'd just seen, and he didn't want to be there any longer. Spying another injured person out of the corner of his eye, he wrapped an arm around their waist, deciding at least as a way out, that they needed medical attention. "Come on mate, taking you to St. Mungos..." He muttered, ignoring the person's insistence that they were fine. Once he reached the lifts, and the doors closed behind him, Lee slumped against the wall. He was a chicken. A damn chicken.
