I watched Titanic for the first time recently and got to the scene shortly after Jack saved Rose from falling off the railing of the ship where Lovejoy notices a hole in Rose's story:
You'll want to tie those.
(Jack looks at his shoes)
Interesting that the young lady slipped so mighty all of a sudden and you still had time to take off your jacket and shoes. Mmmm?
What confuses me here is what Lovejoy thinks he knows about Rose and Jack at this point.
My first time through the movie, I thought Lovejoy was hinting that he saw through Rose's story that Jack saved Rose from slipping and was going with the guard's assumption that Jack was forcing himself on Rose. Which means, through the rest of the movie, Lovejoy thinks Jack attempted to rape Rose and Jack probably knows this as well since Lovejoy told Jack about his suspicions. If anything, it makes Lovejoy the only person in the group interested in Rose's safety since he was the only one to try to look past Rose's obvious lie, which Rose's mother and betrothed couldn't be bothered to do.
But that reading seems at odds with the movie's treatment of Lovejoy as a villain and a toadie to Cal, since he gets to be the one to leave Jack to die painfully after the iceberg hit. He'd have motive to do that if he thought Jack tried to rape Rose, but since neither party talks about the incident I can't tell if that's even the reason for the attempted murder.
Is there any evidence what Lovejoy inferred from Jack's clothing?
