Nah, you can't be this obtuse
Joel gives his coat to Dina to make her warm, which is something that's there to show hard headed people like you that Dina's well being was Joel's first goal out of this thing.
He then goes directly to the window to see what's going on in Jackson and tells the group to strap up, get blankets and get ready to leave in 3 minutes. How in the name of fukk you took that and thought "Joel knows thinks he's gonna hang out , chill and get comfortable in this log cabin with a bunch of fukking strangers".
Abby has her hat on and a blanket and tells Joel her name, he then literally gives her the "

" because he doesn't give a fukk, TURNS AROUND (so he doesn't see Abby anymore) and calls Jackson for a response on the walkie talkie.
THEN Abby tells the gang Joel's name and takes the blanket off and. Then Dina gets used as bargain chip and we get the ensuing scene....
How, how is that bad writing under any measure?
