Well, on Part 1 Bart told Wally that he would end up with Linda and then says Spoilers. But the 3-parter is also a spoilers for Bloodlines (with the arrival of Bart) and for Depth's description where "Artemis rejoins the Team to ensure a satellite's safe launch. But will her first mission back also be her last?". I just inspired myself from the description, but we will find out the truth next Saturday.
