Rick and Morty - is Beth a clone?

I really like the episodes from TheFilmTheorists, this one examines if Rick did clone Beth. (If you have not seen Rick and Morty yet: Spoiler Alert)

He does come to a conclusion. Although Beth still might have gone cloned. What do you think? Is she really on a big space travel while her clone sits at home? Let me know in the comment section below!
