You got it! The answer is "PARTURITION". To explain...
A hypo solves more than one problem... Tom uses one to help feed the baby, in addition to its intended use for the skin irritations.
Pulling hair... Neelix is using tongs repeatedly on pan with the hair pasta. Looks like he is pulling hair.
Not impressed by all the technobabble... Neelix says Paris does not need to impress him with the technobabble when he was making his flight log.

A trait is finally put to rest here... Neelix's jealousy aspect is finally finished with this episode.
A type of ship appears here, but never again on this series... the simulated Jem'Hadar ships only appeared on this episode of the series.
Cracked open... the reptilian baby cracks open its egg.
We've seen this tunnel before... in the flight simulation, we see the same tunnel as the microwormhole in "EYE OF THE NEEDLE".
Your turn.
