As I and a bunch of others have said, the backyard scene HAS to be well before the christening,because Eileen's just a few months pregnant with the kid she's christening. The christening is almost at the END, time-wise, since Murph tells Sarge about them "right after the christening," and Sarge, what an IDIOT (excuse me) tells McCree...
"sort him out"? "rough 'em up"? Yurg...cops.
When Coop apologizes to Eileen for being late, he's not just apologizing for being late (look at her face,). And his.
Second thoughts:Just because I told you to go to hell, why did you jump to the conclusion that I wanted you to go there alone?
