Zack became one of Joey's best friends. He has an interesting career, going from playing extras on TV, to directing amateur plays. Zach does not appear to have a home; he was seen at one time living in Joey's trailer while working on a major blockbuster movie. In one episode, Zach and Joey, both drunk, married in Tijuana, possibly a parody of Ross and Rachel marrying each other in the season five finale of Friends. As a tribute to Joey and Chandler, Joey and Zach argued like a married couple, Zach playing the part of the wife. Zach's final appearance was in "Joey and the Big Move". Núñez was absent from the last five episodes, including the finale of the series, because he found another job. Zach's absence within the show was not mentioned, nor was the character at all.
