I enjoyed the first part a lot.
I'd have to say this was probably one of the most awesome attempts to steal Pokemon ever(Well Leon had a pretty awesome one too...in it's own way) in my opinion.
Meowth not being fired...I don't know if I'm shocked or not. At first I thought it was just all part of the plan but after a while it seemed like he actually did want to switch sides and that, it was only a moments doubt though. I liked how it was done though, Meowth was still being all friendly and then when he went to go to the phone the sudden change of the moment was great, expected but still great I'd say. I love Meowth's evil laugh too.
Cilan...man he's got a sommelier license for everything doesn't he, can't wait to see what's next. I loved his scenes.
Ingo and Emmet are pretty freaky...which is awesome, plus they're awesome at the same time, I'm glad the writers had them in this(If they didn't then it would have been pretty stupid, I mean they are in charge of the Subway and the Subway was the focus of the episode, still they could have done something different and not include the twins, so I'm glad they went with this one).
Zager is doing some cool stuff too.
Oak was in the episode and I seen people mention he was mentioning Tracey, that's pretty cool.
I like how we got to see some screen shots of all the places in Nimbasa city, going to look forward to exploring all of those areas.
I loved the episode and now to watch part 2.
