The shuttle explodes, giving the prisoners a chance to escape. the other Uhura confronts the other Chekov but is forced to abandon her revenge when the prime Chekov is injured. with Kirk and Uhura still onboard the Romulan ship, the others make it back to Enterprise. McCoy and Chapel begin operating on Chekov. as Kirk and Uhura decide how to destroy the Orb it is beamed out.
Sometimes Uhura and other Uhura look very dissimilar. same goes for Chekov. it would be easy enough to tell them apart from hair styles and uniforms, but making them look so different is off putting. i still find the other Uhura/Chekov story to be fairly uninteresting.
six out of ten.
