So, we know that Vee was friends with Masha and everyone else while disguised as Luz, so, did Luz start hanging out with them or did she just abandon them?

And, if she did, how did it make the kids from summer camp feel? And, if she didn't, wouldn't they be able to tell a difference in her sudden change of style and personality?

We also know that Vee didn't hang out with them after she stopped pretending to be Luz because Masha had never saw her in her new form before, and Vee didn't know Masha got a part-time job at the museum, so they obviously didn't hang out during the events of Thanks to Them.

The only tiny bit of conformation we got on this was during the end credits where we saw Vee (in her new form) hanging out with Masha. And, that was obviously after Thanks to Them because at this point, Masha has already seen Vee's new form.

The only other way we could explain this is if Vee told the kids from summer camp that she was a shapeshifter after Yesterday's Lie, but, if that was true, Vee wouldn't have lied to Masha about being new in town.
