This had to be my favorite moment in the series because what happened afterward. Megan and Conner were about to kiss each other, until the Sphere interpreted their sexual tension. Later, they both act if this never happened when regrouping with the rest of the team.
This had to be my second favorite moment because HOLY SNAP! Young Justice showed Robin's face. It is so rare in comic animated series and movies to showed Robin's eyes. The most famous for doing this was Teen Titan. The series even teased the audiences when Robin almost revealed his face every time, but didn't happened. They don't even revealed his name too. I don't know why producers of comic animated series don't wanted to show Robin's face.
