Saints Row The Third Easter Egg - Every Zombie Has a Silver LINning

In the mission when you go and kill Zombies and push the infected containers into the water, listen closely when you and Viola are talking. She`ll say something like "we could of manufactured Zombie Homies. I guess that would be something new." Then your character will say something like "well actually I had this friend named Lin..." and then you are cut off by Viola, and she starts saying some other stuff.

Note: All you Saint`s Row Professionals should remember that Lin got killed in Saints Row and then after that if you called Eye-For-An-Eye you would unlock her for a Zombie Homie just like Carlos in Saints Row 2, and Zombie Gat is unlocked at the end of the Game.
