Why did you change Groundheart...

This a scene of When Spottedpaw confronts Groundheart (Groundheart was deputy/second in command before Spottedpaw) And Groundheart gets sick of it,he's had a bad life and now he's now only filled with hatred due to Lily's evil side teaching him her ways of evil (and Groundheart is like 17 in human years) So basically Groundheart was Lily's partner in crime
