In Chapter 9, Lyra intervenes in an argument between Rainbow Dash and a group of mares who hate her because she's dating a human. When Honeydew takes a step towards her and threatens to shut her up, Lyra incapacitates her in a second and a half from across the street, telekinetically forcing her to the ground before hitting her with a sleep spell.
And freaks out the other two mares by making it look like a Neck Snap - which is something she could have easily done.
Lero diving into the water to save Honeybee who, at this point, had been harassing him and his herd. Double points for pulling it off single-handily.
