Ward was revealed to be a double agent working for Hydra. The things he did early on didn't fit that plotline at all, and all of a sudden he's looking like Mr Evil Face every time he's in a room alone, whereas before he'd continue to look concerned and worried for his team members when he was alone. I know it's just a comic book show, but the way it was handled really bothered me, and then he was just sticking around and being evil without anyone knowing for several episodes after, and it just felt tiresome and stupid. Kind of like a lesser version of the fucking awful "Captain America was a Hydra agent all along" comic that was happening around the same time.
As someone who stopped watching, I was wondering, how did they ever resolve that plot point? Was Ward somehow a triple agent, or did he turn good, or was his secret discovered? I wanted to know, but the episodes started feeling painful to watch, so I never found out.
