Kidnapping
He'd been in a shocked sort of stupour when Bellatrix and Lily faced off, yet he'd held his ground and stood beside Lily, looking for any open opportunity. When he spotted it and lifted his wand for an immobilising spell, he cried out in surprise as he felt chunks of snow hit him on the head and back, turning quickly to see the avalanche that was threatening them.
With a loud an unintelligble yell toward Lily, he launched into her to try and push her out of the way, knowing that if they were caught under it, they'd be done for. The two who were after Lily were obviously intent on doing harm and James didn't know if they'd manage to out-duel them or not. He wasn't even particularly sure who they were, yet something about them looked familiar, and Lily seemed to know who the witch was, at least.
"Lily?" he questioned in concern when he'd managed to mostly avoid the falling snow. The bit that hit him was running down his back and he gritted his teeth against the cold. James made sure to look around them and continue to hold his wand aloft, hoping not to be caught off guard.
