I thought he paid to commission a Schultz sculpt, but it came back too small or looked bad or something and then he told everyone to get Denny's head instead. I think that's his explanation for why some of our money was spent, but he has nothing to show for it. I think the rest was spent paying Yunsil (or he used money from the Django deposits, similar to a pyramid scheme). I think he already has the Yunsil clothing sets for Schultz.
The Calvin project has always pissed me off more than either Schultz or Django because that project was so old (pre-dating even the Marshal) and it got basically zero attention. Like, everyone just completely forgot about it, including Pedro, even though it should have been finished before any of these others even got started. Once the Calvin clothing sets fell out of Yunsil's queue (presuming they were ever there), Pedro never followed-up. Maybe if he'd finished one figure at a time, starting with Calvin, it wouldn't have gotten out of hand with deposits for later offerings being used to make progress on previously unfinished figures, and even then they weren't finished.
