Earlier, Silver Spoon finally standing up for herself against Diamond Tiara is pretty cool.
Twilight and Rarity getting back at Trixie for manipulating the others to vote Apple Bloom out by putting fire ants in her bed is as funny as it is awesome.
In episode 10, after Spike learns that Silver Spoon is the current candidate for going home, he decides that he is not letting that happen. So he convinces Silver Spoon, Applejack, and Fluttershy to vote for Luna, which he does as well, sending her home instead of Silver Spoon in a 4-3 vote. We were taught this earlier in the dodgeball challenge, but the point's been gotten across again: Spike is not to be underestimated.
And later, in episode 11, Silver Spoon gets sent home, which absolutely infuriates Spike. After he calls out Rainbow Dash, who he thought should have gone home instead due to her attitude, the episode ends with him swearing revenge.
