MK4 2 is currently split by A3 1 in Moon Knight's chronology. However, there's no break in MK4 2 for A3 1 to happen. There is a break of 9 days in MK4 3, and MK3-4 span three weeks, but I'm not seeing any pressing need to put A3 1 in the middle of this mini; Moon Knight is pretty busy trying to solve the mystery of his return from death. I'll suggest moving A3 1 to after MK4 4.
Also, Prof. Darkover doesn't actually appear in MK4 3; that's just a hallucination.
