As Enterprise's CMO, Dr. April was something of a pioneer, designing a number of new procedures and medical instruments, largely out of her own necessity. As of 2270, many of her innovations were still used in starship sickbays.
She and her husband were traveling to Babel for the Ambassador-at-Large's retirement party when a ship was flying into the Beta Niobe supernova at warp 36. Upon the Enterprise's entry through the supernova, she was also the first to notice the strange time-reversing properties of the reverse universe; her Capellan flower, which only moments before had been dying, had bloomed anew.
When she, Robert, and the crew of the Enterprise found themselves growing biologically younger, she looked after the "children" while Robert took command of the ship once more. After returning to their universe again, she expressed a desire to live her life over again, but Robert talked her out of it, saying that such a chance an opportunity was for those whose lives were unfulfilled. He didn't believe they could possibly improve on what they had already been to each other, a statement which elicited a kiss from her. (TAS: "The Counter-Clock Incident")
