I'm starting to think I missed something really big this time. Arthur brings Mohinder in and tells him they need Moh's help to complete the formula. I thought they had already completed the formula! We've got synthetic Nathan and Tracy (and whoever else) and Daphne last episode telling Moh "that thing you're trying to do, they've already done it" or something like that.

So is Arthur just lying to Moh to manipulate him? Or did I miss it big time this time? And if Arthur's lying, why? To give Moh some sense of purpose, earn his trust, just keep him busy for awhile?

Maybe they want to be able to control what powers they give to others, rather than just giving others the chance to be "special".

For example, Mohinder got a random series of powers. And Dr. Zimmerman didn't seem to know what power Tracy might have. Like it was unpredictable after giving the child an ability.

Maybe they want to be able to control what ability is in what injection?

Just a theory. :]

maybe there is a third part that belongs in the middle??

From what I understood when Angela was talking about the formula, it only works for certain people. Like there's the genetic code for powers in specific and there's another genetic code that makes it so that the body can support powers. Hence why she said that even though nathan didn't have the genetic code, his body had traits that showed he would be able to support it.

I'm assuming the formula either doesn't work for most people, or has an adverse effect on most people, and they need someone to make it so it works for everyone.

Or they just needed someone to push the two computer screens that had the halves of the formula together...

I like the idea of a 3rd part in the middle, but also he needs the true blood as Kaito told Hiro

That bugged me too. I kept thinking, why don't they just cut and paste those suckers into one image? ctrl+x/ctrl+v people!

Don't be so silly. It's cmd-x/cmd-v. ctrl is the copycat version created by the Sylar company.

Maybe the "true blood" is the middle part of the formula that's missing.

I was surprised that Mohinder found out that he wasn't "cured" in the future and yet was willing to still inject Peter as a "test" that he knew would be futile...b/c obviously it didn't work nor did Arthur take his ability away since he was still a monster in the future...
