When a letter concerning a high profile cold case makes it sound as though the killer has returned, Lisbon must postpone her plans until the case is solved.
Lisbon cracks the code in the letter which leads her and Jane to a beautiful resort. Jane books them rooms for the night and gets Teresa a special dress for dinner.

The next morning, Jane is still being held. Lisbon appears tells him she feels the same way. Jane leans over the table and kisses her as TSA yells at him to stop.
