"Look, Cisquito. Maybe he could. I'm not saying he shouldn't. But I understand it's not something that he can do lightly. At least it shouldn't be. There's always consequences. You know that as well as I do." Hartley lifts his hand so he can run his fingers through Cisco's hair, hoping that he can find the right words. "Barry still can't trust me, because of whatever I did in that other timeline. He was my friend and now he can barely look at me. If things had been different, you might still hate me. We barely managed to take out the time wraith last time."

Cisco has to remember all that, of course he does. If Hartley hadn't figured it out in time, Barry would be gone. The way Zoom was. "I'm not saying Barry can't do it or shouldn't do it, I'm even sure he wants to do it. But he... He has a lot of power and... And..."

It's not really usual for Hartley to search for words like this, but here he is, pressing his lips together in frustration and finally huffing. "I'm trying to think of a different way to say that with great power comes great responsibility so I don't trivialise this with a comic book reference."
