Lily is my one favorite character concept in the whole game. Her backstory is great. It really gives perspective about SM. Most of them were regular folks, elderly, children, men, women, farmers, intellectual etc... Most of them didn't ask to join the Master army. Lily shows that pretty well. Also, it is awesome that Obsidian dared to go so unconventional with a grandma companion. (is there a grand-ma companion is any other game in the world ?) The problem is that once you recruited her, she is lacking in dialogs. If you compare her with Raul, Arcade, Veronica, Cass or even Boone, she doesn't have much too say, which put her in the sideline compared to other humans companions. Considering these companions, and other nightkin characters like Tabitha or God, Lily doesn't feel fully fleshed out, which is sad, as they came up with a great concept and didn't used it well enough. But still, she is better than Rex.
