Hearing all the angry conversation Lily realized it was partly due to a perceived lack of granted authority and it might continue if the issue wasn't addressed soon but she didn't hold any hope it would be an easy fix according to the legends and myths surrounding demi gods.
So knowing she isn't a known quantity Lily looks for a clear space of ground and pulls off her heavy pack and guitar setting them and herself down on the ground and rummaging through her snack haul settling on BBQ Corn Nuts and her Water flask.
Desi had been really surprised when she found herself in the back of a car sleeping and saw a group of punks wandering by that promised a bit of adventure so she got out and followed them only to watch as they got in a fight with a critter like a dragon as one of their number did some mumbo jumbo which opened a portal.
When the portal opened and to her disappointment none of the punks got even a scratch (A scratch meaning the need for EMTs) she flipped a gold coin she'd found (stole from an idiot that showed it to her breaking the rule of never show your treasures to strangers) and it came up heads so just as it closed she dove through.
It was easier than she hoped to take advantage of the Chaos and the focus on the guy called Tony to slip off to the side and just blend as if she belonged while making sure to do as little as possible to attract notice. Once in position she checked her throwing blades and the nifty chain whip a gift from the whore slash goddess who abandoned her to her dad and the harpy she called granny.
Not sure how they'd react to her just tagging along she was sure if they tried anything she was going to make several of them bleed or escape; maybe both.
