This “Before They Were Stars” entry is a request from our own TK, a fan of both Mad Men and Star Trek: Deep Space Nine, who was quite happy to find out that Mad Men star Kevin Rahm made a guest appearance in a 1999 episode of DS9 as Ezri Dax’s brother. There doesn’t see to be any clips of Rahm from the actual episode out there, but you can see him in this Don LaFontaine-voiced preview.
