I've caught up on the show, including tonight's episode. I have a lot to say about it, but I don't want to ramble. I'll just say one thing.
If the show follows through and Ward is actually a double agent for HYDRA, then it's earned an endless amount of goodwill and I will follow it to the end. If it lacks that courage -- if Ward is actually a triple agent or going under deep cover -- then that will be it for me. The episode that reveals that will be without a doubt the last episode I ever see, I don't care if Robert Downey Jr guest stars.
And to answer your question Dex, tonight's episode definitely spoils Winter Soldier.
