Everyday getting a slice of cheese thrown into his face by the other member of the Decay of Angels, Nikolai, could get annoying sometimes...
Sigma, tries walking away to escape the cheese-tosses from him briefly, but Nikolai kept pestering him. A well-timed pleading for peace falls on deaf ears. At last, when all else fails once more, Sigma's anger gets the best of him. But in his frustration he has an epiphany - if he cannot overcome this annoyance, perhaps he can covert it back to Nikolai's end.
When the next slice of cheese flies, aimed at Nikolai, Sigma's hand flies faster still. And now, the once tormenting slice is hurled past Nikolai... Great.
Nikolai at the same time ducks under the flying cheese as Sigma retaliates it, avoiding being hit. However, it did hit someone... You.
