Yeah, me too. David Robert Jones was so interesting I was kind of disappointed they killed him off; I wanted to see him make Olivia pass test two! Though thinking about this again does remind me that in the context of Bell's apparent helping of the other side (probably in part coerced/not as extensive as it could have been) as explained in the S2 finale, it does make Jones' apparent desire to kill Bell (if we can take Nina's word for that, and Jones' behaviour does seem to imply it) more credible. I was always somewhat dubious of the straight-up story Nina told that Jones was jealous Bell never appreciated his abilities and fired him. He seemed too...religious in his convictions that were all based around Bell's writings (even if he did maybe remove the ethics chapter?). But if he thought Bell had abandoned the cause and was now working for the other side, he may have felt obligated to kill him.

Although that still doesn't explain why Bell was funding them. The idea that that was misinformation planted to discredit Bell seems...I don't know, overly convoluted since it was from a credible source and never referenced again to explain it was a lie. I STILL CALL SHENANIGANS!

Regarding the typewriter though, that was Bell's typewriter - Walter found it kicking around the lab and yes, surmised the manuscript was typed on it based on the elevation of the "y" key, but he clearly says it was Bell's typewriter. Which isn't to say that an interesting twist might not be that Walter wrote the manuscript on Bell's typewriter but can't remember it, but the working assumption, at least, is that the manuscript was written by Bell.
