I'm under the influence of recent conversations with hearsawho here... I'd like a missing scene from RotJ, after Leia tells Han that Luke is her brother. Something about him putting together the idea of those two being siblings and the big kiss he witnessed between them in the infirmary on Hoth. (Go any direction you want: het, slash, threesome, OMG-you-two-are-sick-and-I-don't-want-anything-with-either-of-you, whatever.)
