One of the ongoing plot points of season 1 of Agents of SHIELD is that everyone still thinks Coulson is dead.
For example, in the episode where Sif comes to Earth, the agent asks her to not reveal to Thor that she knows he is still alive. However that hasn't really been brought up this season and with each passing episode it seems that more and more people know the agent is alive and that Fury left him in charge of rebuilding SHIELD.
It seems impossible that at the very least Stark would know about this agent. With the long reach that JARVIS clearly has and Maria Hill always knowing the agent was alive, it seems likely. Since there was no mention of him at all during Age of Ultron
(even with the arrival of the Theta Protocol helicarrier Fury only mentions "friends"),
And season 2 of Agents of SHIELD hasn't addressed this, is there anything that lets us know where this situation stands?
