Francis just made it back to his apartment building after a long day at work, he walked up to the check in window, where you were standing

He was about to say his usual "mm hello..." But something was different when he looked at you.. those eyes. They were black for a moment.. as he mumbled

are you sick or am I just seeing things...

He looked at you suspiciously as you stayed silent, just looking at him

Are you a Doppelganger?
