User blog comment:Erockrule/Next Time On Young Justice "Cornered"/@comment-24.0.17.131-20130105203849

There is a clip in the latest trailer with a character that looks like Despero and Captain Marvel fighting. The background in this clip is obviously the Hall of Justice, which leads me to believe  its Despero that will be the gladiator.

There is also an image in one of the trailers with a red gated pyramid formed over the hall of Justice and Captain Marvel flying through the window......I assume this is all the same episode.

Maybe the Reach sends him after the team as a contingency to eliminate the team so they cannot warn anyone about what they learned in "Before the Dawn"

I have no doubts Mal Duncan will put on the Guardian suit in this episode and the Guardian suit was already shown in the Hall. I forget what episode it was though.
