Jack is intensely grateful for the assist there, Rukia. He rolls to make absolutely sure he is out of the way before Rukia is tossed free. Those bullets look like they're doing some damage, so let Jack follow up with an elemental attack of his own.

Electricity seems to arc up Jack's blade, before he brings it down in another slash, deep into the Rex's leg. Thunder Slash. It works, but this time, Jack digs his heels into the dirt, stays in place in close contact with the Rex. Powerful muscles ripple as it tries to shift around, snap its jaws down at Jack, but he doesn't move. Focus on me, big guy. I'm the tastiest morsel out here. Something bigger's coming, as the dino gets angrier, but if it gives his companions a second to get their breath back? So be it.
