Remus smiled a bit at the muttered excuse, but said nothing. Letting Severus get acclimated enough he wasn't fully impaired was more important than teasing just then. No matter how much he felt the urge to do just that.
Instead, he just let the other man go cautiously, testing the sensory input at his own pace. But, when dark eyes opened to stare at him, Remus frowned in puzzlement. How could Severus pick up his scent when Remus himself couldn't pick up Severus? "I think..."
A quiet sound from behind them brought Remus' attention to his own memory self shifting his weight on the rocky beach.
"I wonder..." he mused. "I was here, so there's a memory version of me, which means my own scent, even thought I don't notice it because it's so constant. But you weren't there that day...not even physically here now...it makes sense. Still, odd."
Realising he was talking to himself and not really answering Severus' question, he turned back to the astonished headmaster. "Sorry. Trying to sort something out. But, to answer your question, yes."
