In the 2013 Disney movie Frozen, there is a scene where Kristoff is thrown out of Oaken's Trading Post into the snow after offending Oaken. As his reindeer, Sven, comes over to him Kristoff declares that he found them a "free" place to stay - a nearby log cabin. Here's the transcript from the Transcripts Fandom (emphasis mine):
Kristoff: No, Sven, I didn't get your carrots. [Sven huffs his disappointment] But I did find us a place to sleep. [referring to the dilapidated barn behind them] And it's free. [inside the Oaken's Trading Post Anna watches in shock as Oaken gets back behind the counter]
At no point prior to this scene was the cabin mentioned - I don't believe it appeared on-screen either. While it's possible that Kristoff saw the cabin as Oaken threw him from the store, I don't think his dialog matches this scenario; something like "Hey look, that old cabin looks like a good place to sleep" would have made more sense. Instead his dialog shows that he already learned about the cabin but this didn't happen inside the store.
Kristoff could have noticed the cabin before going into the store, however not showing that scene makes the scene in question feel redundant to me.
When did Kristoff learn about the unused cabin next to Oaken's Trading Post (and Sauna)?
