3) “The Watchful Eye” season-finale, 10 p.m., Freeform. Elena was a minor crook, pressured by a corrupt cop to try a tricky scheme: Fake her resume, work as a nanny for Matthew’s son and find a gem.

In a fairly good episode, most of those are answered, with a few things left in case there’s a second season.
