"Mimi" took her over to "see the brides on the tree", as "Auntie Nicole" asked her whether she did earlier. She kept looking out the window and barked at first when she thought that she saw birds, despite that "Auntie Nicole" kept telling her that they were "on the tree over there".
"Mimi" eventually had to take her over to the tree, and she looked over "Mimi"'s shoulder even then at first.
As for Reilly, she got that the "birdies" were "on the tree over there" when "Auntie Michelle" took her to it right away.
Of course, neither Reilly or Camille get that the "birdies" are ornaments, and "Momma/Auntie Nicole" wanted to take an ornament off the tree and show them "the birdie" to see how they'd react to it for that reason. "Auntie Michelle"/"Mimi", though, misheard and thought that "Momma/Auntie Nicole" was being "sadistic" by tricking them about a "burglar" being around. "Mom-Mom", on the other hand, understood what she said and thought that she was being mean overall.
Update [12:45 AM EST on Monday, December 4th]: "Momma"/"Auntie Nicole" finally got to show Reilly and Camille two of the ornaments to see how they'd react. Though Reilly actually saw both and Camille saw only one, their reactions to each were essentially the same: curiosity and desires to sniff-vestigate. Reilly also, however, licked her lips after she sniffed the cardinal ornament, so she may have wanted to eat the ornament—then again, she had been distracted by Camille's reception of treats from "Auntie Michelle"; so, she may have been licking her lips for treats!
