At any other time, Remus would have laughed at being told how to deal with someone who was drunk given who his friends had been in school. But, he wasn't going to take the time to enlighten Harry when Regulus needed his attention most in that moment. "Thank you."
Shaking his head at the offer to talk, -- like that wouldn't just make things worse! -- he said, "We'll be fine. Don't worry about it. Go on. Get out of here."
Turning to focus on Regulus, Remus thought for only a moment before summoning Dolan to help him get the other man down to their quarters. The elf had been Regulus' accomplice all night, no reason to break up a team.
Once back in their bedroom, he settled Regulus into bed much as he had six months ago when a drunken Regulus had shown up on Remus' doorstep. He banished his clothes, pulled the bedclothes up around him, extracted a promise from the house elf not to tell Regulus Remus had been up all night, and then stepped back from the bed, cancelling the spell so Regulus could come to.
