Auggie and other kids are in the Matthews living room for a 'book club' with Cory sitting at the dining room table. In one scene where Riley and Maya are competing to be Farkle's choice in the hallway at school, you see Cory stop and talk to them for a moment and then continue on. In the next scene, the book club meeting is still going on with Cory still at the dining room table.
In the episode "Girl Meets Smackle" (#1.8) Riley and Maya both met Smackle, however in this episode, Riley acts as though she never even heard of Smackle before. This episode was filmed before "Girl Meets Smackle", hence the inconsistency.
During the awards show, there is an In Memoriam segment and Farkle is visibly upset when Chelsea the fish is shown. This aired before Girl Meets Fish (s2e11), which features the Chelsea the fish plot line.
