So far Katherine smiling has been rare. In fact, have we ever actually seen the woman smiling yet? I can't say that we have. Fanatics have been wondering if Katherine was ever close to the group, but it appears she was.
Whatever Gary said or did it brought about this friendly gesture from Delilah's father Lenny. It's both endearing and heartbreaking how close the gang and their families are given everything that has transpired.
