Bunny's timer automatically expires after five minutes, he has to wait for it to run out and there's no way for him to 'pause' it. But he doesn't have any reason to ICly suspect Gen of defection at this point so I think he could be easily persuaded to give the shard to Gen for safekeeping.. and also because I think it would be funny for Barnaby to be betrayed by Gen this event after backstabbing him in the last event LMAO

So yeah as long as Miru is cool with all of the above, I'm happy to go with that!
