Ganon's yet to be revealed, but his only two appearances make him seem like kirby to me, talks but never has been shown doing anything.
I agree with many others who think MK died instead of kirby. I think Kirby will either remain mysterious, or he will go all out at one point and take out at least 3 characters on-screen. If there is some final battle as it was suggested by the end of the episode, I think captain falcon, fox and samus will die in battle. Fox because it completes all 3 dead space animals, captain falcon as there would be too many good guys left who remain alive or taking a bullet for pit, and samus because, after thinking the scene just before dedede died, samus pulled luigi out of the room making me feel she was ordered to make sure luigi doesn't see who killed dedede and to play along with the aftermath.
Not sure exactly about samus, but I'm picturing the last battle to have Ganon to wipe out a large amount of the cast, grabs a seriously injured samus, grabs her by the neck and says she's failed his orders and does a flamechoke ending her life, while a defenceless luigi witnesses all that at a distance.
I don't think Wario is directly responsible for any of the big incidents, but is responsible for the smaller acts such as selling out the info luigi and samus spilled to him and the probable murder of yoshi. To me he's got a LOT to offer to the bad guys, because he has a lot of information that he can sell to them. Like any greedy man, he sells out any secrets for his personal gain, but does not care about any large scale issues such as the fall of the mushroom kingdom.
I believe the story would be flawed if olimar has been given this much screen-time if he is irrelevant to the plot. He doesn't seem like he has connection to anyone, and only seems to be achieving his own personal goals that don't conflict with anybody else. However, I'm starting to think he may have had some connection to some murders. Perhaps he's been selling them pikmins to sadistic looking ice climbers.
Okay, Lakitu may have told the world that Bowser's castle is falling, or that MK is MIA, but have you people forgotten that the world that's depicted is dark and dying? It's corrupt and is probably full of lies. For all we know Lakitu may have been paid by someone else to make that announcement. That being said, anything Wario says is probably a load of bull. Trades information, but got nothing information about Ganondorf. Well yes if one doesn't know something, they don't know, but he responded as if he solely wanted more information without giving any back.
I'm honestly wondering why someone would stick bowser's head under mario's blanket. At first when I saw a big lump under the blanket I thought it was someone out to get mario. Before revealing that it was yoshi, I was thinking kirby, but kirby has nothing to do with mario so far, right? Plus I did hear a sound being made when mario got up and finally noticed something peculiar with the "thing".
So far, i'm thinking the ending of the series will best be concluded the same way most Saw movies end; the Antagonist dies, while an unexpected character working with the antagonist the whole time will be the last one standing. really I don't know, TWBB continues to suggest more and more possible outcomes, which is probably why it's been getting so much hype from each episode.
