Could mosa have seen Imu?

What if mosa was a former king who saw imu in the previous reverie(4 years ago) and escaped to elbaf, loki might be saying "if i was there i would killed them all" cuz he might be thinking that the gorosei are just old weak men. What if thats why imu sent the gods knights to kill loki cuz he might have tracked down that mosa might have told him?
