[S5E7] O Come, All Ye Thankful HOT!
When Cisco and Caitlin discover that Sherloque Wells' Earth doesn't celebrate Thanksgiving, they attempt to fill him with the spirit of the season. Their plan backfires, however, when Sherloque points out all the bad things that happened to them in the past year and asks what they truly have to be thankful for in the grand scheme of things. This, plus a tirade about Thanksgiving being a celebration of colonization and ethnic-cleansing, lead Cisco and Caitlin to abandon their plans for Thanksgiving Dinner at the West-Allen house in favor of hanging out with Sherloque to spend the day venting about their problems, eating pub snacks, and drinking heavily. Cisco proposes a toast to "The Thankless" and the three seem content up until Killer Frost takes over Caitlin's body and browbeats everyone into going to Barry and Iris' dinner party.
