It is great how they keep on finding ways to get Lily leaving Marshall back into the story and at the same time not only make it funny but also use it to make that part of the story less likely to hurt them later as all their friendships are just getting stronger.
In this episode this happens between Lily and Ted. She hears an old message from the time she left where Ted calls her "grinch". And it is such a good idea, because obviously this is what Ted thought of her back then. And we also get reminded that she left all her friends and Ted was not just mad because of Marshall. But yet he still loves her as we see he very well remembers what would make his friend's Christmas happier. And her coming traditionally with a beer to make it up was also sweet.
