Because I don’t want to do my homework right now. This is probably going to mainly concern the preview. 

[EDIT] Added another theory.

Topic #1: Tieria’s Shower Scene

What’s there to theorize about this you may be wondering? His longer than normal hair of course. There are several plausible explanations, I think (from the smallest leap to the largest, more or less):

 

1. QUALITY
2. Flashback to after the party in 8.
3. It’s a dream/hallucination/etc.
4. Flashback to some unspecified time in the in-between years (and for whatever reason he hasn’t cut his hair for a while, maybe he was in despair mode for a while and let himself go, maybe he decided not to cut his hair until he got CB back together, I dunno, this is all pretty baseless)
5. Tieria’s hair grows really fast.
   a. This is normal. He cuts it every day.
   b. It’s not normal, perhaps due to purple disheveled II doing some mindfucking.
6. Flashback to Tieria’s activation (dunno why his hair would be noticeably longer than in the OP shot but throwing it out there anyway).

 

Other things: My first thought was that it looked like Tieria was having one of those quantum-brainwave-headaches. Perhaps purple disheveled II is dicking with him and maybe Marie will pick up on it and be less useless.

Topic #2 Purple Disheveled II

Obvious things:
 - It’s Revive’s twin (well, more likely than not)
 - Wearing a red/salmon jacket. 

Conclusions/thoughts:
 - Might be a female-identifying Innovator since s/he’s wearing not-grey and according to the writers only the women and Meisters get to wear colored uniforms. It also seems to go with the male/female pairing of Innovators (of the two pairs we know of for certain, both have a male/female voice actor pair and Hilling and Ribbons are pretty opposite in terms of gender presentation, Tieria and Regene are pretty similar though so I dunno how well the pattern holds, I guess you could argue that they developed differently since they haven’t been together much at all)
 - Probably won’t be alive/with Ptolemy-CB for very long (maybe this is what prompts Tieria to reveal the Innovator secret?). I have no doubt that this one is a spy/saboteur rather than a defector like some people have speculated (I mean, it’s possible, but having a character ‘defect’ when they’re introduced is highly suspicious if nothing else). 

 

Er.. well, I’m just going to leave it there for the moment. Possibly more later.

[EDIT]

Topic #3 MISTA BUSHIDO

Now, if I’d started writing this right after I woke up this morning, it would probably be more coherent (this was one of those I-was-pondering-things-while-half-asleep things). It made a lot of sense at that point but it’s probably pretty out there now… BUT ANYHOW, I propose the following:

Mista Bushido is another of Ribbons’ agents (that is to say, aside from the fact that the entire A-Laws operation is under Ribbons’ control, Bushido’s got some kind of more direct relation to Ribbons). I’m thinking a deal-with-the-devil kind of situation since he’s got his fancy license-to-do-whatever-the-fuck-I-want just like Revive but he’s not necessarily under Ribbons’ direct control (more like, Ribbons wants him in play, in the A-Laws, so he gave him his special license/whatever–possibly extending to Ribbons having recovered Graham from the fight with Exia at the end of S1, but that’s more of a stretch). Anyway, I had other evidence when I was half asleep this morning but I either forgot it or made it up because I was half asleep so… yes.
