This is probably one of the better way's to show that a character is bi and or gay.

It's revealed naturally as a character trait rather than the character just blurting it out or being asked about it.

It's not made a big deal about but isn't made so subtle and under the radar that you could argue that isn't what the scene impys.

And it's not shoved it during the last 10 seconds of the series or revealed after the series has already ended.
