Does reluctance to obey orders count? Shen isn't outright refusing, but there comes points where he basically needs to be told to do shit as opposed to taking any initiative. And even then, they probably need to be repeated a good few times before programming really kicks in and he gets off his ass.

He's also ditching a few practices and has taken to leaving Virgo HQ for a few nights a week to just kind of wander and occasionally busk ~in disguise~ so technically that's practice maybe. Any funds gained from this are dumped in the nearest begger's hat, and he's back by sunrise to then sleep half the day away. Rinse, repeat.

...basically any trouble/shit he starts is incredibly passive aggressive and could be chalked up to him being a whiny little turd because whining is definitely happening. HE'S TAKING EVERYTHING PRETTY HARD, OKAY.
