It's so soon too. I suppose this is a tiny gesture of confirmation to my Sumeru theory that we'll be getting most of the pieces of the story soon along with tons of misleading information and red herrings to prevent us from figuring it out.
But one of my theories is now dead in a ditch. RIP Brighella. Apparently MiHoYo decided to go with another Columbina? Not sure how that'll work.
Signora herself was a combination of Capitano and Columbina so having now a pure Columbina character feels weird. But I suppose since we do have a Capitano too and Scaramouche is also an evolution off of him it might work out. But based on her character my old theory on how Brighella would go still works surprisingly. Columbina was a simple character in the beginning because in the commedia dell'arte women weren't really developed into characters. This is why Signora is a mix of both Columbina and Capitano. But Columbina is also sometimes associated with the Zanni just like Brighella. She's also a gossip which could work in the same way as Brighella's conman. The only thing that would really change is that I don't think she'll be playable. The reason is that while Brighella is a light-hearted character Columbina is more serious. If she's going to be the secondary Harbinger we fight in Fontaine it'll be more mean spirited than with Brighella. She might try to twist public perception in Fontaine against us and maybe even the Archon. That's a serious no no girlfriend. 
Side note: It's also interesting she's the one lying on Signora's coffin since they're both inspired by the same character. Btw what did they bury? Signora was sliced up and disintegrated by the Shogun. Empty casket? Creepy. 
Finally Columbina as mentioned with Signora is on the side of the Innamorati or lovers. This was seen with Signora because she pledged herself to the Tsaritsa after being recruited by Pierro. But another Innamorati character is Tartaglia so we may see some interaction between them as well. At the same time based on who Columbina is maybe Childe will be reluctant to accept her help. I'm also very distrusting of her. She seems to have ulterior motives.
It also looks like my theory on Arlecchino won't be changing either. Listening to her in the video you can feel her anger. Of course back then I thought she was a he but either way she seems to have had a thing for Signora meaning that part of the Columbina role is still firmly with Signora. But what that could mean is Columbina will be pined after by Pantalone another story angle in the commedia. And she herself seems to be interested in Dottore though that might just be her flirtatious side and she's just interested in Dottore because that part of my theory has worked out. He is our Harbinger for Sumeru.
Finally it looks like my Pierro origin story is right. They even reused the quote they teased a long time ago which I used to figure it out.
Take a look at the eye.... not to mention the eyepatch. He's Khaenri'ahn.
O and I was wrong about him not caring about Signora. He seems honestly upset and vowing to complete their mission and make the Old World Signora's tomb. It's funny because this might make him the link between the Tsaritsa's plan and the Abyss/Khaenri'ah's plan.
How about you guys? Did anything from the video surprise you? Were any of your suspicions confirmed?

PS: This video being Signora's funeral does also go to show that she's not going to be playable. Fs in the chat for her simps. Sadly that also likely means none of these guys will end up playable. (maybe long after the game's over and MiHoYo just wants to suck up the last drops of profit from it lol)
