Two focals is not 2 people in one tag. A focal is what you're looking at, the focal point, so the two people in your tag is your focal. Focal is like focus, and it doesn't relate directly to the number of renders or people in the piece. You know? If you had one person on one side of the tag, and one on the other, not relating to one another, that would be multiple focals, which is not cool ;]
No I just found you were funny haha. In a good way obviously. You made me and my GF lol.
