He also appeared as an extra in these two DS9 shows:
* What You Leave Behind: Part 1 (2 June 1999) - Extra
* What You Leave Behind: Part 2 (2 June 1999) - Extra in final holodeck scene (uncredited)

The standouts here for me are his tirst, The Offspring (the wonderfully moving episode in which Data constructs a daughter), and Second Chances, when Will meets his double – a man who still loves Deanna.
