So far the only ones that match this agenda is the first one, Tracks, and potentially the last one, needles... as they wouldn't feel it however they would be shocked at first thinking that they were going to be stabbed by needed. The other three have a lot to do with C, B, and A ranks.

just let me talk to zel when he gets on, i'm pretty sure its one sense for D and E
