Anyone else think that bringing back Wally might have been a side effect of the legion's mission? Is is possible they went back to get Barry and Wally (and family) were riding the lightning by coincidence? It looks like the legion trapped Barry in the lighting rod the Brainiac 5 was holding ar the end of the story.

Also-Any thoughts as to who the third legionairw is seen runniing our of the Fortress of Solitude with Val?
