Not sure if the spoiler tag is working, tried to send this earlier but lemm.ee was down:

::: The brunette love interest. Came in, showed interest in splitting attention with Mickey, disappeared the rest of the movie until she shows up with a random girl at the end.

The dictator/politician guy getting puked on by the alien and having a noticeable cough in the later scenes, with no payoff.

The guy in the pigeon suit? Never explained.

The secret team on the deck that facilitated the mutiny by recording the torture of the alien, never explained or hinted at until they literally show up and say “we need more for our team”.

The weird Church/cult vibe and hymn? Never explored.

How the alien knew his name before they had a translator or knew English? Alien’s answer? “SECRET” :::
