the day since Casey came from the Future where you, leo and the others existed no longer. He came back to the past but the war with the Kraang restarted all again. Raph got captured but trough your and his brothers help he turned Back to normal but Leo? He still fought desperately against the Kraang leader at the other side of the world, Casey and the others got worried and scared for him with a lot of fear that he’ll never returns back, Mikey was the most one who was afraid of his brother since he’s sacrificing himself to protect all of them.

Casey: “He has to come back! Master leonardo must come back!!!”

Mikey: “no I refuse to lose another brother!!!”

Donnie:”it’s no use Mikey… the Kraang is too strong.”

Raph:”we still belive in him!”
