I normally would've QT'd her but I knew she came from the same tank as the other frog. If there was something in the tank she was already exposed as was the new frog. Both came from the same PetSmart about a week apart from each other.
I was shocked about my cousin. I could see some of my other family members doing it, but not him. He's 22 years old. Old enough to take responsibility for the animals he brings into his life. It's not her fault he chose her.
Thanks to everyone for all their help by the way!
