What happened to Number 1 in the second episode. The dog isn't around this time and he's a key part of the marketing. Picard's faithful companion just disappeared. He's not around to bark when the Stargazer doctor shows up and he's not around when the Daystrom scientist has tea. Picard decides to go back into space and doesn't seem to even think about his dog. When he tells the Tal Shiar guy he has to stay behind to handle the harvest, Picard doesn't say, "and also take good care of Number 1." They'll have to make a Short Trek to explain Number 1's disappearance from this episode.
