[Q]: So was Jon Snow brought back to life in Game of Thrones to kill Daenerys? To me it makes sense, I'm not sure if I missed something along the way. It also backs the point that Daenerys would do no good for the world as the queen of Westeros.
[A]: Is this the purpose of bringing back Jon?


[Q]: In Interstellar, when Murph visits her brother and his wife, she notices that their son is coughing hard, and she offers to arrange a visit from a doctor for him. The brother and his wife refuse, however, even though she warns them their son will die otherwise.  Did it signify anything? I thought that maybe it signified that there is an anti-science movement because of the blight. The brother certainly seemed to dislike his father and sister's scientific pursuits.
[A]:
Why did Murph's brother and his wife refuse a doctor for their son in Interstellar?
