He also called kakashi's power borrowed...which seems strange if he's borrowing it himself
Yup, he also called himself Madara, said the Kyuubi attack was a freak accident, and claimed Pain's Rinnigan were his to begin with. So we shouldn't really take what he says too seriously. One thing we know for certain about Tobi is he twists the truth to gain the mental advantage, and that's what he is trying to do with Kakashi and it almost worked if not for Gai and Naruto.
I can just see it next week, His mask is destroyed, finally we find out his identity, shocked faces all around, Naruto:, Kakash, Gaii: You, Bee looks at the three curiously All: Who are you?, Bee face faults.
I still think it's a Madara related person,
this page when he's describing the founding of the village to Sasuke, he clenched his fists like he had an emotional attachment to the situation. Obito's perents were probably not even born at that time so he has no involvement to it at all.
Why isn't Tobi using his rinnegan abilities?
He is, he used the Rinnigan's ability with the chains and rods to block the Bijuu's power, Plus he just got the eyes so he probably hasn't mastered the other powers yet.
Yes but it was his latest kamui and most important of all naruto managed to put a clone on tobi's dimension and this clone has kyuubi chakra cloak, wich implies that tobi cant use kamui anymore too otherwise he will be destroyed.
i think we gonna have a stop in the fight and get a lot of talks and flashbacks.
Well Tobi is stuck at the moment, if he went back to the real dimension he'd be destroyed by the Bijuubomb, so he had to take a hit. he's still capable of using the eyes but he die a painful death if he did. However I do agree we'll probably get another flashback from next week on how Tobi became.
EMS, the eyes won't bleed, we saw this with Sasuke as well, he used the eyes on the Zetsu and suffered none of the drawbacks, the bleeding I beleive was shown to depict the fact you will go blind if you constantly use MS, with the EMS that disability disappears.
