Antipater and Cassandra

With Antipater coming back to Macadonia with this sort of power and authority, it's hard not to see this as one of the lowest points in Olympia's life. He basically has all of the trappings of legitimacy that you could possibly have to be the one who gives orders in Alexander's stead except for Alexander's body. Ptolemy is of course, coveting that at home, talking to it maybe when no one's looking. So he's got a lot of reasons to want to see her gone.
