'Annika' Season 2's Premiere Sings a Song of Scottish Seals
Annika is not the type of series that stands on ceremony or sits around waiting on a lot of preamble. It's part of the benefit of a series where every week is a new case, and there's not much in the way of significant arcs throughout the season. Even Season 1's "mystery" of Morgan's paternity was played down to the point where it wasn't something the show was hiding, as much as it was yet another thing our titular detective avoided ever talking about, until, of course, she dropped the bomb at the very end of Season 1 that Morgan's dad was, in fact, ex-high school boyfriend Michael McAndrews, now her second in command at MHU.
DCI Oban: It's voice activated so you can talk to the car if you don't want the pyschologist.
Season 2 picks up literal moments after that reveal, the same night Annika nearly died in the boot of a car after being held at gunpoint earlier that day. Naturally, these near-death experiences have her nattering on about Scottish songs, the Child Ballads specifically, so named because Francis James Child collected them. She's using one as her reasoning for hiding Morgan from Michael. (It's a myth where the father steals the child upon learning of it, and both dad and baby die.) She's interrupted by Michael, natch, because a new murder, recorded on a phone two nights ago, was just dropped at the station while they were at the pub.
