In this episode, we follow the three main characters' personal stories that don't intertwine at any stage.
Hilary is stuck in an elevator with her disagreeable mother and her weirdly-looking neighbor Tilda. Mom talks too much about private matters and then the lift gets stuck, so the three women get an unwelcome chance to spend some "not-so-quality" time together. With mothers (and family stories) like that, one is not surprised that Hilary is not inclined to procreation.
Mercy and David spend time of better quality (or just pleasure?) having sex in her dingy apartment and discovering she may be pregnant, even if David's sperm is not top quality. That is left undecided (stupid cliffhanger) but I think Mercy is on the family way, David will move in that direction, and "bye bye" Hilary who'll get a chance to be a strong, SINGLE, independent woman - not a spoiler, just my take on the situation.
My least favorite part was Margaret and hubby stuck at the morgue and waiting to identify the body who could be their son. Clearly not a good moment, but Margaret is such an unpleasant character, tunnel-visioned, stuck in her grief, I don't care about her sorrow. Obviously, the body is not Gus's. My take is that Gus will be found and this family will go back to normal, or the parents will split... whatever, I don't care.
PS Another reviewer mentioned a "patriarchal influence" on the script, but where exactly? I never saw a series more drenched in estrogen, it's children, mother, lovers' trouble, and relationships all the way, just one step from pure, undiluted soap opera. Not necessarily a bad thing, but "patriarchal"? LMAO.
