I discussed this privately with a few friends but I actually love the idea a lot so I’m sharing with everyone. 😀
So far in this very long arc, there were a few occasions the focus drifted away from Ciel & Seb. The first major time was at the very beginning of this arc

with Ed being the reason Lizzie went to the Sphere music hall in the first place and the second major time…

led to very unfortunate circumstances. T_T
So I was saying to my friends that I’d love to get some more chapters not focusing on Ciel and Seb, especially now that they’ve been put in a rather awkward position…

and might need the help of others to clear their names if they’re really arrested. And since Soma is hurt, more Ed-centric chapters could be more likely and I’d personally love that.
First of all, it’s hard to believe that Ed won’t question if real!Ciel truly isn’t involved with the Sphere music hall considering that Lizzie is with him and that she left the house for the Sphere music hall over two months ago.
Secondly, Ed is currently the only one who was also there at Weston when UT explained about his latest BDs to Ciel

so, should he recognize UT (even if we know Ed can’t see anyone else when Lizzie is here), he might be able to suspect that something is up with real!Ciel.
As for a team up with Soma, the reasons I find this idea so cool are because Edward and Soma both are characters who are very close to our!Ciel + at the time of ch143, what they know about the current arc is complementary, meaning that if they were to assemble their information, they would both easily realize that our!Ciel was framed.
To explain: what Soma knows and believes is that…

someone who looks exactly like our!Ciel attacked him and Agni, leading to Agni’s murder. So now he’s pissed at our!Ciel because he doesn’t know about the existence of the twin (since our!Ciel never mentioned anything about it).
Meanwhile, Ed just found out that the twin is back…

and that our!Ciel is believed to be behind the blue sect arc for different reasons.
So should Ed see Soma and find out about this…


If Soma tries to argue that our!Ciel did this even if this doesn’t sound like him, then Ed will at least be able to tell Soma that “wait, he actually has a twin brother who just came back???”, which could make Soma realize that his friend is innocent and Ed that the twin is up to no good (especially if he remembers about Weston previously to finding out about the attack on Soma and Agni).
Add Sieglinde…

who heard this, who can confirm that Ciel and Seb are the ones who brought Soma to her and who researched about the blood samples Seb found in the Sphere music hall + Nina…

who helped Ciel and Seb with getting into the Sphere music hall that one time, they will barely need Violet’s confirmation to understand that “Lord Sirius” is in fact the twin (even though I think Violet’ll confirm it either way, because our!Ciel helped him and his friends).
Violet (and also Lizzie) is more likely to be necessary in order to convince the other people involved in this arc that our!Ciel is not Lord Sirius: like the Double Charles (who may end up accusing Ciel of the Parliamentarians’ murders next), Randall (because Abberline won’t be able to convince him on his own I guess) and maybe even Alexis.
TL;DR Ed investigating some more as Ciel is possibly arrested and meeting with Soma could surely be one way for the entire truth to be revealed + also for Soma to stop believing that his best friend attacked him.
I just hope Ed does realize, one way or another, that there is definitely something not right about the twins and Lizzie.
