Drunken Marriage Bargain

Jaune manages to defeat Cardin in a spar after training with Pyrrah over the semester break. Team JNPR and RWBY agree to go out to a club to celebrate but why does Jaune then wake up surrounded by the sleeping forms of Ruby, Weiss, Blake, Yang and Pyrrha? A headache, strapped to the bed and six rings to boot this is quite the drunken marriage bargain if he can survive it that is.
