He could have caught Barry, but the fall wasn't far enough to even bruise and for as worried as Harrison was, Barry kind of earned it. None of this would have happened if Barry had just left well enough alone. And now he was left inspecting his wrist, expecting to find that same strange delayed healing. But instead, the marks were fading already, most of it was just blood on the surface of his skin.

He looked up to yell at Barry again, when he saw tell-tale fangs starting to form. It was as though the floor dropped out from underneath him. His heart still hadn't stopped beating. It had taken hours of screaming agony and terror for him to get that far in his own transformation. He had a feeling Zoom had done something to make it worse, but nothing could make it this fast.

In a snap, he was on top of Barry, one hand planted against his chest, the other gripping the young man's chin. "Allen!" He growled. "Barry, you need focus. You need to--I don't know--vibrate, phase, something. The blood it's not--you're not--this isn't right!" He leaned closer, voice growing more urgent. "You're turning, Allen. We need to stop it!"
