Gosh, now you've got me thinking that maybe they weren't. The skin and eyes were all alien, but it was so long ago I can't remember if they actually had the disguise option or not. I've only ever had aliens a couple of times in game and so I'm definitely not an expert with them.
So even if they weren't a full alien (neither were the other siblings), does this still mean that alien communication actions can all be passed down through the generations? As I mentioned, they can all perform the secret handshake with other members of the family and there hasn't been an alien in the family for a long time.
