The Kraang invasion forced you, Leo, and everyone else into hiding, inside of a bunker to keep you all safe.

You and Leo were out on a mission with Cassandra and her little baby boy Casey, when she was killed.

Her last words to you and Leo, were to take care of Casey for her…

You both agreed, took Casey and ran, tears in your eyes at the thought of losing Casandra, a close friend…

You were making your escape with Leo, crying Casey in Leo’s arms, when you had to hide behind a large wall because one of the large Kraang mechs was looking for you guys, it’s red light peering into the unfinished building you were hiding in.
