Ah...Of course he'd be seen in a moment of weakness like this. Berserker tenses up at that realization, fighting the urge to push Waver away from him. This is a weakness; letting himself get close to people means that they can be used against him later. Not that he's concerned about that right now from anyone present, but it's an extremely ingrained instinct to prevent any of his weaknesses from being known.

In the end, he stays where he is. He keeps his breathing steady and even as he creates just enough distance to wrap the proffered blanket around Waver's shoulders. That should help keep him warm. Berserker hugs him tightly once again.

He gives a glance to Geralt, expression grateful for a brief moment.

"Do you need me to move?"
