Ferrer died from throat cancer in January, at the age of 61. His character was written out of the show in the March 5 episode, Season 8, Episode 16, "Old Tricks."

Granger had been stabbed and was at the hospital, but when Hetty (Linda Hunt) went to check on him, he was gone. As a nurse explained, "One minute he was here, and the next minute he wasn't. ... He pulled out his IV and walked out." But he left a note for Hetty, saying he had "unfinished business to take care of" and he would leave it up to her to explain his disappearing act.

Overall, fans seemed to find it a fitting tribute, appreciating the song choice and the fact that Granger was not killed off, he just -- as one tweeted -- "left pretty much the way he came in, unannounced."
