Continuity mistake: In the flashbacks to when Boomer was going to sing at school, the audience never changes clothes or seats despite every scene being a new event and year.
Continuity mistake: Mikayla complains she's defenseless after Boomer throws her machete overboard from the yacht; later in that episode she pulls out a back-up machete to fight the giant toad.
Answer: No. Although Mikayla and Mason occasionally referred to the mother, her whereabouts were never revealed.
