Vash can't help but to smirk a little bit. Happy to see a bit of his old friend back. "I could go again if you think it would help you." If Vash was being honest he did have some drugs still in his system that were encouraging to say a much more enthusiastic yes. He knows this is likely a result of what has been done to him so if Azwel really wants to rest he's more than happy to ignore that desire until it passes. "But maybe you should rest. I think death by exhaustion might be a real thing."
