I was thinking speed force too. [This is why Hal's primarily been with Jay so far. He's calming and Hal doesn't feel like he needs to protect him like he does with Wally. The younger speedster is fragile right now so being with him is hard because all Hal ends up doing is trying to make things better for him]

When Barry came back, he said he felt like he had to be careful or he'd be pulled back in. So...maybe he was. [He kind of hopes it's that, honestly] And if he was, that means we just gotta figure out how to get him back out.
