Star Trek: Voyager 138: Ashes to Ashes (2000)

Synopsis
The Borg children introduced in the earlier episode "Collective" figure prominently in this story, in which Voyager crew person Ens. Lindsay Ballard (Kim Rhodes) is brought back from death via genetic engineering developed by the Kobali. Though grateful for this new lease on life, Ballard has a lot of difficulty adjusting, especially since she no longer knows if she is Kobali or human. Meanwhile, Seven of Nine's (Jeri Ryan) latent maternal instincts are stirred when she is placed in charge of the Borg youngsters. "Ashes to Ashes" was originally broadcast on March 1, 2000. ~ Hal Erickson, All Movie Guide
