Oh, yay! I love it when Merlin shifts into animals! And the letter bit, with Arthur somehow managing to decipher Merlin's horrid scrawl, was very sweet. The bit where "Lemon Meringue" changes to "Love Merlin" is perfect. And, of course, YOU HAVE MAGPIE ARTHUR! I've been gushing over magpie!Arthur since syllic's Three Tasks, so you hit on one of my major kinks. ♥
