Siblings may fall prey to rivalries or bad blood, but they’ve always got each other’s backs when it comes to enemies. And this toddler in the video (above) from Columbia City, Indiana, USA, is proof.

The two-year-old thought his elder sister was in danger and being attacked, so he rushed to her rescue. He courageously tackled her adversary, fending him off. However, Ryan missed the crucial fact that his five-year-old sister, Ruby, was participating in a wrestling match at an elementary school meet, and that he had just knocked down her opponent.

Ryan tried to drag his vanquished opponent away, but the referee broke up the altercation and handed him over to an adult. The person recording the footage echoed what everyone was thinking: “That is the best thing I’ve ever seen.”
