this list might contain spoilers for the books. these are my personal theories and things that could happen/I would like to read in the books.

• lyanna stark and rhaegar targaryen are the parents of jon snow (it's confirmed that lyanna is his mother)
• daenerys, jon (who are both targaryens) and bran stark (?)(who has his special gift/power) will be the three dragon riders
• jaime will kill cersei ("the valonqar shall wrap his hands about your pale white throat and choke the life from you."); I personally really want them to die together though
