Here is the one you were waiting for: The one where Sweets informs Cullen of what he has learned through the session at the end of the episode. Hope it's as good as you hoped.

Deputy Director Cullen
We have had a great amount of progress in today's session. It has become very apparent to me that their relationship is nothing like anything the bureau has seen before, and will have to be treated differently. They have a very close emotional bond that I had not foreseen. They are a great team, and are very pleased to be working together.
I had not realized how much time outside of the professional manner the two spent together. They appear to be very close friends and are very concerned for the safety and wellbeing of each other. This may come as a problem in some situations, but I can only see this as a plus in the field. They "have each others' back," so to speak.
There has been some inference to an intimate relationship between the two. I am not saying that they are romantically involved, but that they may be in the future. This should not come as a surprise to you, seeing as they are quite the talk of the building. I am simply informing you that it may be more likely than you may be willing to admit. I doubt this would hinder their performance on the job, they are both professionals.
I hope that my information will assist you in making decisions about them in the future, and that you would see me before you involve either of them in anything that might have a great influence on their relationship.
Sincerely
Dr. Sweets

Have you noticed how Cullen's letters are very short, where Sweets feels it necessary to elaborate on everything? That's just how I see him. He hides behind it all with formality. Whatever. Leave me a message.
