After seeing this and hearing all the comments on the interviews with Sasha in them I BELIEVE that she is a very calm and reserved person in COMPARISON to all of them cause they are all pretty big personalities and pretty everywhere and crazy so it’s not she is left out she is just a different personality compared to all them cause all their personalities blend right together I think when she is with just one or 2 of them she stands out a lot more because she can blend with them better so it’s nothing against her or them leaving her out
