Sarge realizes that Mays fascination with him has to do with the other version of him.
With his violent tendencies, Sarge initially assumes that May must have killed Coulson.
Then he realizes it must be the other thing, the source of this episodes title.
If Mays powerful connection to Coulson wasnt about death, then it must have been about love.
Sarge thinks he can use that to turn May to his side.
He implants another parasite into some helpless rando so you can show her what its like.
So far, he hasnt succeeded, but they keep on trying.
He just wasnt the kind of outsider they were looking for.
Back at the lab, Benson and Yo-Yo make another discovery of the Shrikes.
He says it was the hardest decision of his life, but also the right choice.
That conversation also has a lot to do with the May/Sarge storyline.
Just as Sarge thinks hes convincing May of his mission, she turns on him.
After taking out Snowflake, she starts garroting Sarge as he sits in the drivers seat.
Her relationship with Coulson wasnt a matter of love OR death; it had to do with both.
Now, she finally gets the drop on Sarge.
After hes knocked out, and handcuffed, May heads back to base.
But at the last minute, Enoch sneaks into Fitzs cell and unleashes some kind of gas.
