Brilliant and intence Episode.
Purple Dragons are back
Casey taking out the Purple dragons was great
Raph vs Casey fight scene was epic and intence.
Casey spotting Raph on the roof was a reference to the original movie
April and Splinter fighting alongside the Turtles was wicked
Raph and Casey fighting the Foot Bot on the train was also epic
Eastman name on Casey's hockey stick
Irma in the episode and talking
Casey thought the Turtles were Italian
We know why Raph hid into his shell, he saw a cockroach that Mikey was holding.
I think Donny should start thinking about putting up some security in the Lair.
