Audio problem: When Joe and Old Joe are talking in the cafe, Old Joe asks Joe how is his French coming and Joe replies with "Good. You gonna tell me I ought to be learning Mandarin?" and Old Joe then says "I never regretted learning French." Old Joe's jaw is never shown moving along with the speech. (00:41:40)
Audio problem: When Joe is telling Old Joe that he'll never meet his wife in the future to prevent her death, a shot from behind Joe is shown, where he says "she'll be safe", but his jaw is never shown moving along with the line. (00:48:15)
Chosen answer: Writer/director Rian Johnson has stated that he didn't write the script with the intention of having Abe and Kid Blue be the older and younger versions of the same character, but that he likes the widespread fan theory that they are, acknowledging that the dynamic he wrote for the two characters very much lends itself to that interpretation. So that's an official "No, but it's a cool idea".
