Central City

"Central City sounds like a good destination, I've always liked that Killer Frost person... as in attracted, not as in I want to help her cover the World in ice" you say to Supergirl

Supergirl nods in agreement before speeding off into the sky... like a flash... get it, flash.

You speed off after her and quickly catch up just before you get to Central City. You land and have a look around. You're right near the police station and you think you can make out Patty Spivot just going in but you could be wrong.

Your super hearing alerts you to some officers calling over the radio about an attack, ice based. That would be Killer Frost.

You're sure you could find other girls if you wanted to, Golden Glider for example.
