Probably the fact that Jason has a twin brother named Andrew. The Quartermaines never knew about Andrew since Susan Moore left him with Betsy Frank. Alan took Jason back to Port Charles and was raised with the Quartermaines and Susan planned on going back for Andrew but she died and Andrew was raised by Betsy Frank. Andrew was later growing up in an estate home and he eventually became a Navy SEAL and began calling himself Andrew Cain.
