This question already has an answer here:
So, as has been known for a while (and which should surprise absolutely no one), Agents of SHIELD and Age of Ultron will impact each other's stories. Can someone please name, without any spoilers, where Age of Ultron should fall for the best cross-MCU story?
(Clarification – Here's what I mean by best: My mom watched all of AoS S1 before watching Winter Soldier. Clearly a bad move, as Winter Soldier was obviously meant to be the big reveal for what then shakes up the remainder of AoS. When, relative to the recent/upcoming AoS S2 episodes, should Age of Ultron be watched to make sure all the big reveals happen at the proper time?)
