Which episode is this photoset from?

[daymarket.livejournal.com]

Hello all! I hope this is allowed. I saw this photoset on tumblr, and while I can identify the first two and take a crack at guessing the last (I haven't watched the last couple episodes yet but I know the gist of what's going on), I can't for the life of me figure out where the third set comes from. I would be very grateful if somebody could point out the episode to me. Thank you!
