A small one. After the "earthquake" that was really the spell being cast. Tess and Anna immediately forget their fight and check to see the other is okay.
Anna and Tess finally switching back after Anna (in her mother's body) gives an equally heartwarming speech to everyone at the rehearsal, finally accepting Ryan as her stepfather and into the family. Doubles as a Tear Jerker when she tears up upon mentioning how good her birth father was and how she wanted to let her mother know how she felt about it. If that doesn't melt your heart, Tess mouthing "I love you", just before the switch-back occurs, certainly will.
Afterwards, during the wedding scene, Tess and Anna embrace, having walked "a mile in each other's shoes" and tell them how much they love one another. It's a significant Character Development for both of them, especially after seeing them fight through most of the first half of the film.
Anna and Jake dancing and sharing a kiss.
Equally doubling as a Moment of Awesome (and Awesome Music) is Anna and her band performing "Ultimate" and their families and friends clapping to the beat.
Anna reading Harry's paper about how much he looks up to her when attending the parent-teacher conference; given how much they were at each other's throats through the entire movie beforehand, seeing them have their first civil moment together is really quite touching. Doubles as a Funny Moment when Harry asks his "Mom" not to tell Anna, because fighting with her is too much fun.
Anna (In her mom's body) learning about Ryan's true feelings about Anna and how he wants Anna to like him on her own terms, and that he has always tried to support whatever she set her mind to. Anna is so moved that despite being told not to earlier by her mom, she kisses Ryan full on the cheek; she made doubly awesome when she fully accepts him into the family as noted above.
There's also Tess-in-Anna really discovering how great her daughter's music is. It's implied she barely listened to them perform, dismissing them as "noise". But after being forced on stage at the House of Blues, she finally appreciates the effort and tells Anna "most definitely not noise".
It's also rather cute to see Tess getting into the song once Anna starts playing for her. She even mouths along to the words and has some fun on stage.
Before the audition begins, Peg assures Anna (Tess) that the band will still love her even if things don't pan out. In light of what Stacy Hinkhouse became, it shows that Maddie and Peg are the True Companions in Anna's life and that they have each other's backs. Maddie even tells Anna (Tess) that she rocks harder than anyone else she knows.
In that vein, while it's implied that Maddie is the main frontwoman for Pink Slip, she allows Anna to take the lead for "Ultimate" due to it being her mom's wedding. Now that's friendship.
It’s small, but when Anna has detention the first time, the detention monitor (Ms. Brown) swaps lunches with her for what’s clearly not the first time. Anna even brings Ms. Brown an extra drink when she goes back a second time, for which she receives a grateful wink.
