[S3E18] So Long, Dawn Long EXCLUSIVE
The group planned to hold the tube from this position, but they ended up under attack from both ends after Lor-Zod came back through from the Earth end of the tube. Rocket created a force bubble to protect them and block the tube. The boom tube began to destabilize due to being held open so long, and the team's attackers fled. Zatanna created a portal to take them back to the school bus.
