Season 3, Ep. 1: The Beanie Exchange
While soaking up the last of Summer over Labour Day weekend on a getaway with Archie and Veronica, Betty and Jughead once again steal the show. During the later part of the episode, the lovebirds are sitting by the fire and Jughead puts his beanie on Betty saying, "From now on, we're partners. In Serpents, in life, all of it, OK?" Ugh, swoon.
