Supernatural: Whats the last episode Jo was in?

The last one i saw was "no exit" ... is she in any other episodes after this one ? if so whats it called ?
Update: Wait ... the last one i saw was Born Under a Bad Sign she had a sort of falling out with the boys after discovering from the possessed Sam that their father actually got Jo's father killed.

These are the only two i have ever seen Jo in ...

I she in any other ?
