Blaine was sitting cross-legged in the middle of his bed wearing a neon pink feather boa and a pair of Superman boxers on his head. He had no shirt on and was wearing his Buzz Lightyear pyjamas as he took another drag from the joint Puck passed him, and then immediately broke into another giggling fit. He was laughing so hard he was snorting and leaned forward to rest his forehead on the top of his bed. "Doesn't even matter! I'm gonna get a magic carpet like Laldaddin and FLY all the way to Kurt and tell him I love him!" he declared, flipping his head back up with another snort of laughter. "And it's gonna be PINK! I LOVE PINK!"

His hand dove into the large bowl of candy sitting beside him and he stuffed the whole handful into his mouth. Puck had just confiscated his cell phone after realising Blaine was stone-texting Kurt. So far, Kurt had responded. But now, Blaine was planning alternative methods of communication after deciding carrier pigeons wouldn't work in case the bird crapped on Kurt's beautiful clothes. Blaine didn't want to die, so he couldn't risk that. Puck had come over after chatting online to Blaine and listening to Blaine colourfully and passionately abuse Karofsky, and telling Puck how much he didn't need Santana Lopez fighting his battles because he was a fighter himself. It was the first hint Puck got of Blaine's concealed past. Blaine was a boxer, though when Puck tried get more details, all he got in response was "I'M HOTTER THAN ROCKY!"

But yes, Puck wanted to see Blaine high and what better time to slip him a little weed when Blaine was peeved about Santana and Karofksy? Blaine's dad wasn't home, instead being out somewhere with his friends, so this was a perfect time.
