What did Minato say to Naruto at the end of The Lost Tower?

[Sasori11/8]

Hi. Can anyone tell me what Minato said to Naruto in silence when they were parting near the end of the movie The Lost Tower? Also, if you know, can you tell me how you found out? ...because I tried looking through the entire movie again, but I couldn't find where Minato actually said what he said in silence out loud... Thank you! :D

He kinda knew that naruto was his son from the future due to how he had Kushinas face and his hair... He meant on his "if" was that he knew ... So technically he was a proud dad even though he wasn't yet a father you get me?
