It was good to see the show based upon the further development of an integral pillar of House's life. Wilson's character has always revolved around his friend's life. Now we get too see why that is so. House to him, is not only the friend he wants, but the friend he needs. And we see that in the episode, which is aptly named.
Wilson's identity is & and has undergone sever changes, since the death of his last love. And that loss has forced the him to seek his own identity, not from the views of others but by his own standards.
Thanks to writer to building another great character.
