Lucifer looked up at the sound of someone shouting. "Hmm? Freaks? Where?" He responded perhaps a bit too casually considering what it was he had just heard. At the sight of the young man, he lifted his free hand to wave as he attempted to approach, still holding on to Liz's hand. "Oh, hello there! You look familiar, have we met before? Oh, wait, give me a moment to think...I'm sure I'll get it." 

As soon as he got close, he placed his free hand on the young man's shoulder and held him in place close to him, seeming not to worry at all about the fact that there were potential killers in the area. "Hmm...maybe it was...oh no, I think I'm wrong after all. My mistake, I thought I met you back at the shop the other day, but your face is completely different up close, isn't it? Aha~ Terribly sorry about that!"

He continued rambling for a few seconds, still gripping the man's shoulder very firmly and with an oblivious-looking smile on his face before he turned to see two other figures further down the street. "Oh, hey! Do I know you two? You'll have to forgive me, my glasses are actually starting to mess with my vision now, so I really can't be absolutely certain from this distance."
