According to the NBC Days summary for this episode, Rory replaced Fynn, who was on Deimos's payroll. Fynn was supposed to deliver the drugs and then angrily end their association. It made me wonder if Deimos is behind Dario and Summer scamming Maggie, that Summer really isn't Maggie's daughter. Fynn may have drugged Brady for Deimos and gave him those crazy Summer visions, hoping needy Summer would drive a wedge behind Brady and insecure Theresa. Awhile back Victor wondered and immediately dismissed Deimos being behind Daniel's accident, but now I'm the one wondering!
The only way I could have seen Cassandra keeping the baby is if it was by her Paris boyfriend, lying to Yuri that she was a virgin hoping they'd treat her better. But her initial reaction to the pregnancy news says otherwise.
Then David could have rejoindered with "why did you shoot that guy five times in the back?" While her justified anger at Jim was hot for what he did to Laura and threatened to do to Jamie, Brooke's murderous intent was cold, planned! David shooting JR was much more a crime of passion, mere moments after seeing his daughter die in front of him.
