Lena may have been drunk on the beach, far enough away from the battle to be in any danger, but, clearly, Riot and Crash can not get away. They will for now, have to face the past they fear, and return to Celestial. They are needed. They both have unfinished business...She helps them pack up their things, and sends them on a flight home to Celestial.
Crash: I hope you brought a bottle of that green shit for the plane ride - I'm gonna need it.
Riot: Tell me about it, We're totally flying ass backwards by stopping in Raleigh-Durham too..
Crash: Yeah, that's flying....always having to go backwards and out of the way before you can get home...
