This is from Ask Ausiello from ew.com

He calls it spoilers, but I think it will give some people to watch
this season of 24.

I actually like this season alot so far. Alot of the characters are
really good and the storylines are very interesting. Also Tony is
back :)

Anyway on to the great news....straight from Kiefer himself!!

Question: Got any Snapple-worthy scoop about 24? -- Penny

Ausiello: Jack's lover-turned-frozen vegetable Audrey Raines will
play a pivotal role this season, albeit an invisible one. I'll let
Kiefer Sutherland explain: "She's not a physical presence, but the
damage of losing her absolutely [impacts] why Jack might not be able
to engage on an emotional level with other people. It adds a huge
sense of loss that informs almost everything he does." Kiefer doesn't
rule out the possibility of Audrey returning in the flesh next
season, particularly since A) Lipstick Jungle looks to be a goner,
and B) as Kiefer reveals to me exclusively, "[Audrey] has finally
stopped dribbling."
