Is it bad that I just imagined Jiminy showing up like that? Lolz.
And since he's so tiny many opponents simply fail to spot him in time and are doinkt in full surprise.
While that may be true, I just remembered another little but certainly not trivial detail from DDD.
During that whole Nightmare sequence in DDD Sora got to feel the pain and sorrow of the others, the scene with Roxas is even called "Roxas' grief" in theater mode and the more Sora learns the more unstable and angry he gets about what was done to them all:
"Not again. Did they cause all this pain?"
In hindsight, the whole of DDD was in some vein a way to get Sora fired up somewhat for opposing Xehanort even more and if I had to take a bet once he gets to talk to Aqua, Ven and possibly Terra in person his resolve will only get stronger.
It shall be the only truth from now on!
If Pluto is our real main villain, then Jiminy certainly is our real main character....
Sora and his friends do have a power Xehanort knows nothing off in the end. It is called....JIMINY CRICKET.
That scene and his anger is one of the main reasons I think Sora has a valid point as well. They're connected to him and he even feels their pain. I am very sure the scene in which Riku and Kairi turn into Aqua and Terra and back again just before leaving Sora behind wasn't really a nice feeling as well and I'm pretty sure he's understood that this pain is also what Ventus partly felt or feels. (Edit: And let's not forget the pain I'm going through right now because I was curious of what Sora says in that scene and Ventus' theme plays. Holy sh- this is so sad.)
But I still think what he experienced there is just a bit of what some of the others went through. And knowing Sora, he's the kind of person to brush it off with "I'm fine. You guys are the ones who suffered. Sorry I couldn't help you earlier."
