Vengeance

After Into Darkness, Captain James Kirk and the crew of the Enterprise star their five year mission seeking out unexplored territories of space, but they were hardly out of warp speed when Jim hears that Khan has, yet again, escaped. What's troubling is that the only way he could have escaped is with outside help, help from an experienced and perhaps equally dangerous. Who and why? Unfortunately, the person is someone Jim neither wanted or believed possible to do it.
It's hard for the rest of the crew to process the situation, but everyone handles it differently.
