I approve of the Grodd content of this week's episode. I liked how they worked his desire for other gorillas into the way he's removed as an immediate threat. I'm sad that it's going to take some significant effort now to see him again, but I can see quite a few options for it to happen. Wouldn't be a stretch to have the Legends run across him, or have Flash use him against Zoom or another big bad, or even have him become a major villain for a future season. So there's still hope for more monkeying around.
The Hawkgirl lead-in with Cisco and Kendra is kinda cool, although I'm getting a little tired of Cisco freaking out every time he sees something in one of his vibes. The same guy who is so meta-geeked out that he comes up with all the names, has an issue when he sees a winged person somehow associated to his girlfriend? Hell, he should be running toward that. It looks like he's coming around by the end of the episode, fortunately.
The lying-to-Patty continues to be awful. They haven't even tried to do any explanation of why they don't just bring her into the gang. It also seems a little odd that there's no tension between Barry and Iris over his relationship with Patty. You'd think they'd at least need to clear the air a bit, after all that angst over their relationship last season.
In my mind, it's no worse than sending him off on his own in the first place. The whole "I gotta go be myself" thing never did much for me, but if you're gonna use it, then it's not much more of a stretch to say that he'll drop back in every once in a while.
