Anise has fallen head over hooves for Willie, the cannon horse. Cinder, who's got quite a crush on the dark filly, is quite jealous of Willie and somewhat upset at the attention the pinto's getting from Anise.
This scene just came to my mind when I realised Anise has two crushers: Willie and Cinder. And since Cinder has a tendency to be a bit wild and impulsive, I can just see him getting jealous and giving Willie the evil eye whenever he sees him talking to Anise ^^
