Ok, during my third viewing, I finally figured out who David Tennant was playing.
Of the teens, there is the big geek, the twins, Astrid, and then there's one that kind of has a unibrow and is always hitting on Astrid.
Now, there's one adult who looks like a grown-up version of that teen. He only has a few lines here and there, but he's the one played by David.
He also does the audiobooks based on the books in that series. I had no idea til now.
