Going Back To Mount Justice

The Teen Titans get unexpected message from The Batman about joining the Young Justice Team in a secret mission and without a second thought the Titans were aboard with joining but Robin was not.

After leaving them, how could he face his old team or explain to the Titans about his past? He didn't know yet but before he knew it, he was landing inside Mount. Justice on the ship with the Team waiting on them.

He almost forgot his worries when his eyes landed on a similar speedster.

How was he going to get pass this? Will it be bad or good? Will his love for Wally be regained or stepped on?
