Loki just sent them to a random apocalypse without thinking so they could escape
Yes sorry, maybe I wasn't clear. I know what happened to send them there, just question why the filler episode in a six episode series.
My guess (probably wrong) is we learn that none of what happened actually happened. Maybe the next episode opens and it's both of them in the original shelter on the planet with her hands around his neck and we find the whole thing was a mental battle between her charm and his projections. Then Owen Wilson will interrupt with a humorous line "oh, did we interrupt something" and slap some neck restraints on them both.
Then everybody will return to the TVA where the secret of variants is revealed and Owen Wilson begins to question things.
