Also was Sarge stabbing May and putting her through the portal his last act to give them a chance before he turned? Cause I think it feels that way.
The way he was acting afterwards, I don't think so. Seems like he didn't realise/remember she wouldn't die on the other side.
My take was the Coulson side of him and the Shrike side of him were at war, so yeah in a last ditch subconscious effort the Coulson side of him stabbed Melinda and pushed her through the portal to give her a fighting chance, but after that the Shrike side of him completely took over.
Good finale overall, but splitting up FitzSimmons again...sigh.
Thought the exact same thing. This cannot keep happening, especially in the final season.
