As far as #2 is concerned, we've been treated to a very callous and trigger-happy Scarab thus far. Jaime's doing everything he can to subvert its more homicidal tendencies. Perhaps the Scarab is malfunctioning in some way, and could not completely take over its host. I'm betting Jaime will be forced, against his will, to serve the Reach before the season is over.

And #3, Lobo's nickname is the "Main Main". He was, indeed, hired to put on a show for the LOCALS (on Earth), to unmask the Kroloteans. And yes, to distract the Justice League while they play whack-a-krolo.
