The single best line in the film (a lot of which has to do with delivery, as with most great lines) is from Kylo Ren:
“Blast that piece of junk
OUT OF THE SKY”I liked the significance he put into that line also.
I think he knew that it was The Millennium Falcon
No way how
A few things although one doesn’t really count. First of all Snoke says to Ren “Theirs been an awakening,Have you felt it… Theirs one more thing, the droid we seek is aboard the MILLENNIUM FALCON WITH YOUR FATHER”. Also there was a deleted scene of Ren searching the Millennium Falcon (Doesn’t really count). Plus in the Force awakens it would of taken time for Rey to get unconscious Finn on board the MF giving time for Ren to maybe see it. One last thing, Han might of talked about it, described or even drawn it to him before Ren turned when he was younger. These are only inferences but its worth doing them. It makes you think about it more.
