Tying in with Serkis' narration is a clip of Han, Leia and Chewie, and the placement of the "don't get too sentimental" alongside these three characters definitely has an ominous implication. The shot reportedly shows Han looking at Leia before walking towards the Falcon where Chewie is waiting, so it sounds like fans should expect some sort of drama between the two. Perhaps Leia wants Solo to stop going on bada** missions and settle down, or maybe it's got something to do with involving their (apparent) daughter Rey in all this. As long as it doesn't get in the way of Harrison Ford kicking a** and taking names, it could work, especially if it provides a little comic relief amid all the doom and gloom.
