The Wonderbolts are many things. They're defenders; athletes; weatherponies; role models. But one thing they don't typically do is interact with the breezies. Even though the pegasi and the breezies have had a long-standing symbiotic relationship since the founding of Equestria, entomology simply isn't in a Wonderbolt's job description.

You can also imagine her surprise when she discovers that she's not only working alongside a cadet from the Academy, but also an actual Wonderbolt. Seeing this as her opportunity to get back in the Wonderbolts' good graces, Lightning decides to make the best of the situation and impress Fleetfoot with her skills. After all, gathering nectar from a bunch of bugs (read: fairies) should be a cinch for a future Wonderbolt.
