Random things we find out about a VOY character that are never mentioned again

[Oddish]

I'll start...
- Tom was really fascinated by the sea as a child
- Harry was in charge of the Academy news rag
- Chakotay was a champion boxer
- Janeway talks to Voyager
- Neelix is nihilophobic

Any others come to mind?

B'Elanna competed in track and field.

 

[Tosk]

Chakotay was a champion boxer

I'm gonna be an annoying pedant and mention that Chakotay's boxing is brought up a second time, in Tsunkatse.

Janeway fiddles with her combadge when she's nervous.
(This one irked me when I first saw the scene. I thought no she doesn't.)
