I'll try to make a theory- 👌
My theory :
Let's make things clearer first.
In the video, we see Rainbit telling Cheshire to stop bothering Alice, Cheshire then says " Look who's talking " as it was very similar to what happened in the past, expect it's the opposite and has a different visitor included who is most likely to be Falice.
In the past, Rainbit seems to be insulting/talking bad/warning Falice about Cheshire or is just straight up bothering Falice. Cheshire seems to be very annoyed by that and decides to go comfort/talk with Rainbit about it. Rainbit could have been saying " Why not? Plus, it won't hurt to have some little fun ! " with an amused expression or something else that my brain does not know. Rainbit and Cheshire also seems to have a very bad relationship that they fight A LOT.
Now we go to the present.
Cheshire is being too protective with Alice not wanting the same thing to happen again that it
( theory 1 ) ruined Rainbit's plan which is something that includes Alice.
( theory 2 ) annoyed Rainbit that Cheshire is preventing Alice away from her.
( part of theory 1 ) Cheshire knew about Rainbit's plan and decided to keep Alice away from Rainbit, ( part of theory 1 and 2) always telling Alice to stay away from Rainbit, not to trust Rainbit, how Rainbit may look nice and trusting but is extremely dangerous, talking bad about Rainbit, etc. Just like before.
(part of theory 1 ) Rainbit has been skeptical about Alice and that Cheshire has been keeping away Alice from her. Everytime Rainbit invites Alice for a tea party, explore more of Wonderland, to visit Draco Hatter and Catterpillar Funneh with her, etc, Alice either decline saying that she's busy or just ignores it. Usually, Alice never missed out an invitation by her, she starts to become even more skeptical about Alice and how close Alice is with Cheshire, until she found out.
( part of theory 1 and 2 ) One day, Rainbit decides to comfort/talk with Cheshire to stop bothering Alice. Cheshire then says " Look who's talking, " both of them got reminded of the past when it was Cheshire asking Rainbit to stop bothering Falice and now it's the complete opposite.
