Looks like Clara's time on the Tardis is drawing to a close. Either at Christmas or some point in S9 next year. So what fate should befall Clara ?.
. Wouldn't that be better then her being blown up or eaten by something nasty ?.
River the doctors wife died years before her time. Taking her own life in a tragic paradox to save their future relationship/marriage. 11 didn't get to say goodbye to Amy and Rory. Maybe 12 will say a proper farewell to Clara. Would also tie in with a pregnancy. Years later she will have an adult child and grandchild(ren) Orson ?. Makes sense that she would want to say goodbye to 12 and her family before finally joining her beloved Danny in Heaven like Rose and Jack in Titanic. Sad but also happy she would have had a full life.
