I loved this episode. The new character is definitely not boring and would be a great addition to the cast, either as an agent or a regent-in-training. Her scientific perspective on the artifacts-- that everything, from fire onward, has a destructive side until you understand it enough to control it-- would add a new dimension to the warehouse and the show. And, yes, she is adorable.
So Brother Data can now change his appearance. Does this explain Artie's vision or is it a red herring?
And if every artifact has a downside, will Brother Data's serial use of them ultimately catch up with him?
