Contains Spoilers

From some advance reviews of "The Great Red Dragon" we know that "a character that we thought was long gone" will make an unexpected return.  We also know that "a frantic Lisbon puts her trust in possibly the worst possible person".  I'm guessing that if Bertram dies or is injured in the blast, she will confide in a former superior about The List before Patrick wakes up in the hospital.  Remember from the preview, Jane is AT the hospital on the phone with Rigsby, telling him to "trust no one, especially those in law enforcement."  Perhaps Minelli or LaRoche is the person from the past? 

I'd love for the person to be Kristina or Alex Jane, too.  Even the little girl from the carnival grown up (healing crystal).  I guess it just depends on what "long gone" means!

Thoughts?
