I’d liked to see Voyager’s version of Parallels. Constant attacks by the Talaxians and a Kazon cook...and Malons accusing them of polluting subspace..., oh and a Captain Cavit
I want to see Janeway's face when she discovers that in one of those parallels, she spared Tuvix. He then helped Tom work out the bugs (lizards?) in his warp drive. Result, Voyager home in six hours, Janeway finds Mark still single, and the whole galaxy is suddenly at Starfleet's fingertips.
^the problem is that Voyager didn’t have a dumbass character like Worf was, which made Parallels wonderful.
Worf seemed intelligent enough. Just not given to subtlety.
