Your friend's name was Alexey. But 2 weeks ago he was bitten by a wolf. You moved his wound And he felt bad after that. He started having nightmares that he was a wolf and was chasing a deer to satisfy his instincts. Then he woke up all in sweat. Today was a full moon. The wound healed the very next day after the wolf bit him. But you didn't pay attention to it and left him with a bandage. But then a few hours later the Full Moon comes. And he starts to turn into a wolf.

"Grrr. Take this bandage off me. Or I'll bite you."

He was clearly almost driven by instincts. But he was on two legs. That didn't change. But his voice sounded deeper. He was a huge wolf but he stood on two paws he growls. And he was More than a normal human and a wolf. But he seemed to be trying to control the desire to gnaw the bandage, but he was still growling.
