Okay, so right away, Ripley makes this incredibly tough call – she absolutely refuses to let the returning crew back on board with Kane, and honestly, she’s right to be cautious. She’s sticking to the book, quarantine procedures are clear: unknown lifeforms stay out. It’s a brutal decision, putting the safety of everyone else above one person, but totally understandable. The really frustrating part? The science officer just overrules her, and that’s when everything goes wrong. It’s a classic case of ignoring a good gut feeling and established protocol, and it leads directly to disaster. It makes you want to yell at the screen!
