I'd say there's one problem with that episode. It's that there were a lot of moving pieces to get them all into that final place.
Although, after thinking about it, after spending some time with Ballers, I don't think Vince was so disconnected from the rest of cast anymore. In the past Vince is a somewhat low level crime guy and Colin is a THICK, apparently do-gooder officer who ended up going down a bad path due to family loss. Then we come to present and Vince is the one with his act together, although still in shady business ventures and Colin is patently corrupt and mostly a disheveled mess. It's not quite a reversal of fortunes, but enough to show a link between the two and something that will have to come to a head at some point in the season.
What happened during the sex scene with Rachel that we didn't see? I like that she's not perfect and the sting fell flat on it's face. Chill out on the webcam hate. I've heard it's legitimate business these days.
John Carter of the Pacific Coast Highway thinks with his dick, needs Viagra, and is a thrill seeker. Fair enough.
I liked how it call came together at the end. I haven't seen more than the first trailer or teaser and it looks like a lot of it was literally all from this episode. That's good for keeping spoiler free.
