Headscratchers / Roomies!, It's Walky!, Joyce and Walky!

• What is Dina's Abductee power? Every other abductee that was given screen time got so show off their power (even if it was just super-strength/durability), but we never find out what Dina's is.
  • It's entirely possible it's either enhanced intelligence (like Joe) or she's not an abductee at all (like Jason.)
    • Considering we see the aliens going after her the night they try and abduct Joe and Joyce, along with her fainting during the Year Zero episode like the other abductees, she's probably an abductee. Enhanced intelligence sounds possible.
    • She was literally seen among the abductees when Robin snuck on board in the Shortpacked flashback.
• When Joyce and Walky try to elope, they have to find two witnesses. Why do neither of them consider Becky?
