Question: I was so disappointed that Bones killed off Sweets. Why? Why? Why? I really enjoyed him. - Natalie
Matt Roush: By all accounts, everyone on the show
liked him, too, so much so that you can almost look at this as a mercy
killing, freeing up the actor John Francis Daley to pursue his burgeoning career as a screenwriter and director. (Read the post-mortem here.)
If they hadn't killed Sweets, they probably would have had to write him
out of much of the season, and as we've discussed many times before in
this space, the death of a major character can provide valuable new
story material for a show and its characters (in this case, Booth more
especially). Can't say I'm crazy about how quickly they subbed in the
character of Agent Aubrey, who while not a replacement (different duties
and attitude) serves to help us forget, even temporarily, that there's a
gaping absence on this team.
