Sean Cassidy, also known as Banshee, was your best friend when the two of you were a part of the First class. You both got along well, and he loved to be around you. After stopping the Hellfire club from starting nuclear war, and during drafts for the Vietnam war, you disappeared. Alex was drafted, as well as a few others. Sean remained an X-Men those years.

Sean was over the moon at the idea of you returning, and had not one argument and was on his way to your doorstep as soon as he got the address.
