There's only one Andorian episode
Bite your tongue.
"Journey to Babel", "Gamesters of Triskelion", "Whom Gods Destroy", "Lights of Zetar", then throw in "Yesteryear".
and only one visit by relative episode (and they're the same one).
Well, I was thinking TNG eps with that one. It was almost a soap opera of forgotten and estranged relatives.
