I'm sure the entire Klaine fandom has seen this by now (several times) but here it is anyway (you can never have too much of a good thing, right?)
Oh the squee! I think this is my favourite Klaine moment of all time, bar none. It's perfect. It's so adorably, sweet but not saccharine or cheesy. It's touching. It's funny. It has cute Kurt fashion meta. It's Kurt willing and eager to marry Blaine. It's Blaine being so honest and open. It's them both being so head-over-heals in love with each other.
And it's just one more example of why Klaine is endgame.
Of course I'm totally p'd off a little disappointed that they had to cut it to make more room for Rachel and Finn going on and on about an African sow pig helping others and discovering the true meaning of Christmas but it's still completey canon for me so whatever.
