Patrick first met Danny during his first year in the Hufflepuff Basement. He had heard stories about him whispered throughout the school about how he's openly gay and doesn't care that other people think less of him because of it. Patrick did not understand why people just can't accept and love each other for how they are. During his first conversation with Danny, he felt immediately calm in his presence. There's something about Danny that makes you trust him and Patrick started to become friends with Danny at a quick rate. How could he not to when Danny is such a likeable person?
Patrick loves it when he notices Danny sitting in the stands when he is having a Quidditch match. Danny always dresses up in bright Hufflepuff colors and outfits to cheer the team on, and he always brought Brody along in his second year. Their presence gave Patrick a boost, and it usually made him perform better, knowing that his friends and family members are watching and counting on him and his team to win the match. However, due to the intense amount of Quidditch practises, Patrick couldn't hang out with Danny as much as he wanted to, same goes with Brody.
During his third year, Danny took Patrick and Brody apart when he found out that they were homo- and bisexual. He brought them to his dorm and locked it before telling him how proud he was of them and how he now has more LGBT friends to hang out and talk about boys with. Danny also felt the urge to make sure that they knew what they were doing when it's time for them to have fun in the bedroom, so Danny gave the both of them sexual education in private, in a course of several weeks. He made sure to include everything in his private sexual education lessons: safe sex, condoms, STDs (Sexually Transmitted Diseases), kinks, fetishes, sex positions, roleplay, public sex, bondage, safe words, tops, bottoms, versatiles, dominants, submissives and more. When it comes to gay sex, Danny's a walking encyclopedia and he was more than willing to share his knowledge on all these subjects with Patrick and Brody. He even demonstrated a lot of it on them in which he refers to as "practise lessons". In these lessons, Danny, Patrick and Brody will act out whatever they've learned in the last few lessons in which they all switch between top and bottom. This is something that the three of them keep a secret from everyone.
