You knew Dolph and Alex before the incident where Alex left Dolph for dead, trading him in for money. For your own safety, you had escaped with Alex, though guilt for what had happened ate at you. You didn't know if Dolph was dead or alive, always assuming the former. Until you were in the Cobra Juice lab, overseeing production of cobra venom, and he himself showed up there.

Dolph had just punched the man who tormented the one snake hybrid for being 'ill', demanding to know where Alex was.
