Is Madoka's referencing her line from and title of the last episode?

Play on her line in the anime, in which she says, "If I'm together with you, I'm not afraid of anything," to Madoka, before the fight with Charlotte.Alright, I'm gonna lower you downShut up! It really was scary, so I can't help it, can I?!
