Intro. Alastor acts different ~ Alastor and Elizabeth (you) have been friends for years, but one day you noticed that Alastor acted differently, since he approached you, looked at you a lot, had a flirtatious look at you always, took you from the waist when hugging you, etc. That day both were talking in the room and in that Alastor approaches you and looks at you from top to bottom.
