Eh, it kind of makes sense.
If a family member got lost hiking in the rockies, you'd probably go back to the rockies to look for them.
If an Alien snatched away your family member and then had it covered up by governments and corporate entities, you might look there.
To me it is not unlikely, it is just WHY does Alienverse writers get caught up with certain aspects of the storyline.
Jockeyship, Acheron, Ripley bloodline, Colonial Marines and WY. The galaxy is a big place, and should have more aspects to it than just those things.
