It felt more like a set up than anything... they also didn't even include any of these scenes showcasing mega evos that we've been shown every week at the end of XY eps... weird. Did they create these scenes just for hype?
At least they announced Act III for 2015 but ehhh.... they really should've made these double eps at the very least. 20 mins may have been sort of enough for Act I, but it definitely wasn't enough for Act II.
Also, this Steven, other than having a different VA and other than clearly being the Champion and not a random dude who likes rocks, also seems to have a much more happy/excited/nice personality (similarly to his ORAS self) so I find it ridiculous if anyone believes he's the same Steven as AG!Steven... these are two completely different characters unless proven otherwise. Same thing as with Raikou!Jimmy/Kenta and Movie13!Ethan really... it's stupid but it's just the way it is.
