Aside from romanticising Caitlin, Jay Garrick returns to his mentor/helper role this week, mostly in terms of being an excellent scientist rather than a (former) speedster. Still, aside from providing a love interest for Caitlin, it doesn't feel like he's doing all that much at the moment, and while he was important last week in saving Harry Wells, they could get by without him for the most part. Garrick's true importance won't really be until he gets his powers back, something I thought would've happened in this episode, if not before now. They're dragging it out, with no easy way in sight for him to actually get them back, but it's going to happen sooner rather than later, right?
