Here is a picture of Twilight and Colgate hugging. In MLP FiM Colgate is one of Twilight’s old friends who she knew in Canterlot, and this picture is meant to show a reconciliation between the two after not seeing each other much.

Colgate: I love you Twilight, I have never forgotten about how good of a friend you are.

Twilight Sparkle: Don’t worry Colgate, even if we don’t hang out much we will still be friends no matter what. I’ll always be here for you.
