Given that the last episode featured a relationship between a brain in a jar and a sentient gorilla, my takeaway is that this show is just full on embracing silver age style weirdness.
That and the League of Lois literally loses track of the show's universe at the end so this struck me more as a one off thing rather than the main plot.

Eh it's very brief, it's not ruined, yet, so don't go catastrophising.
