Though each episode this season has begun with a bit of conversation from the Last Supper/Upper Room Discourse, in this and the next episode we’re finally getting into the set up and beginning of that last night itself.

For all the weight he’s bearing, Jesus starts off cheerful. He’s happy that he’s able to have this meal with his disciples, with his friends. We know there is deep pathos underlying that cheerfulness when he describes it as “Our last meal together.”
We see Jesus washing the disciples’ feet. They’re all confused by his action, though Peter is the only one putting up strong resistance. In the face of his not giving in easily, Jesus comments, “Sometimes Peter is still Simon.”
The episode also features flashbacks to times in the disciples’ lives before they met Jesus.
