Is this the first time we've encountered an Otherside creature who just...wanted to have fun?
No blood, no nightmares, no fighting, no possession...just everybody having a gay old time with a random lion demon who loves music and dancing.
I'd wager that was less a joyful romp than an exorcisism. Sorawo used her drunken angst to summon up some kind of otherworld exorcist to deal with an otherworld issue.
