THEORY!

The finally battle will actually be a Broadway style DANCE BATTLE!!!!



But seriously, is KR Jam going to be Micchi? Ryoma? Or could it be Yoko? Oh man, what if the Jam turns out to be Yoko?!?!

I heard a rumor KR Jam was a final boss for Gaim at the end. Episode 46 is the actual episode where it all ends. 47 is a team-up like they did at the end of Wizard which made no sense at all.

You can. I think there are better, but I won't argue with anyone who loves Gaim that much.

Proof?

I think it might be from the fact that Episode 46 is Gen Urobuchi's last written episode for Gaim. Someone else is writing 47.

Good thing you put a question mark there because I will argue against that if it wasn't a question

people tend to call their favorite series "the best 'insert word here' series ever!!!"
is it annoying? HELL YEAH IT IS but most people do it at some point. The phrase "best series ever!!!" is largely just subjective anyway so I'd take it with a grain of salt when ever it is spoken or written.

Anywho I really liked this episode it really made feel sorry for Micchy the poor dumb bastard.

Yep, episode 46 is indeed Urobuchi's last episode.

Episode 46 - Fate's Victor (9/21)
Written by: Gen Urobuchi

Episode 47 (Final Episode) - N/A (9/28)
Written by: Jin Haganeya

Whether or not Jam is a tie-in rider on the other hand is something you'll have to judge for yourself. Having read the episode summaries to the end, I'm fairly sure about Jam's role even though it doesn't talk about him at all.

That still doesn't make it a fact then that episode 47 is not the last episode to the story. You are just assuming. Sure, it would make sense, but you have no actual proof.
