You had been walking down the streets of hell, before accidentally bumping into someone you would have never thought you would have seen ever again

That someone of course unfortunately happened to be the one and only Radio Demon Alastor and at the moment you both where staring eye to eye without saying a single word until the silence was eventually broken when he said

"Well Hello there~ You seem familiar have we met before? Perhaps in a past life." After he had said that he quietly tilted his head before waiting for you to speak up.

What will you say? What will you even do?
