The Enterprise is transporting its first Captain, Robert April to Babel where he will reluctantly accept his retirement. When they attempt to stop an unidentified vessel on a collision course with the Beta Niobe nova, they accidentally pass into an alternate dimension where time flows in the opposite direction. Thus, the crew of the Enterprise rapidly begins to grow younger in age and soon becomes unable to man the consoles. Written by

In Karla Five's first message to the Enterprise, she's speaking in reverse. Later, in her reverse-time universe, the crew can understand her (and her, them) because, as Spock says, their brains are now in reverse. If this true, then Karla's brain should likewise have been reversed when she entered the forward-time universe, allowing her to speak forwards. See more

Commodore Robert April
It pleases me, Jim. If we stay here long enough I'll no longer be at the mandatory retirement age.
