Caitlin & Rosa
Being as she was new in Madison Valley, Caitlin didn't think anyone would approach her. It was a foolish notion when you were aware that you had been here before-even if you didn't remember it-and people who were your friends or whatever then would probably still talk to you...even if it was not the same you. Caitlin could only equate that scenario to when she'd met her Earth-2 counterpart, Killer Frost and that was not exactly an equal scenario given that Caitlin had been to Madison Valley...just not this Caitlin? It was confusing even for someone aware of the vast amount of worlds and times available out there.
Despite this, she still looked up, a bit surprised, when the woman addressed her. Obviously, the face was unfamiliar, but by the question and the "doctor" reference, Caitlin understood that this woman knew her from being here before. Still, the way she phrased it: doctor one, made Caitlin think that she'd talked to someone from Caitlin's world. That was the only way she'd know Caitlin was a doctor or had been. She'd been bartending when this place snatched her away.
"I usually just go by Caitlin," Caitlin replied. "But yes, I am a doctor or I was."
