I love it when you see something in the closing credits that is from that day's episode - like the note that Julia wrote Barnabas today.
It would have been more interesting if Trask had spoken through Stokes - or, better yet, Julia. But I suppose that Tony may be (as somebody or other suggested a while back) a Trask descendant. I daresay Gregory had a few unacknowledged children here and there.
Was this the first time that we ever heard the Eliot part of Stokes's name?
