Yeah, I'm very glad. Blue is one of my favorite heroes, and the Reach don't get much coverage. Only animated thing about them I've ever seen was the Brave and the Bold episode with him.
And yeah, Mgann's either needs to learn how to interrogate without eliminating the person's capacity to do anything or just stop it altogether.
Aqualad feels forced, I think. One, 'Aquagirl'? Good god, at least call her by her damn NAME when the guy seemingly mad with grief is grieving about her. The Aqualad and Blank Manta thing is weird, though epic. Official Light member, probably some Reach Beetle upgrades for the Mantas soon, and Aqualad kicked ass. Was cool. But why the hell he cares so hard about serving his father he never knew and turns his back on his morals, I cant really comprehend well.
