May

When Lily walked into the house that day and saw May making the trails of marshmallows and graham crackers to lead the roaches out Lily finally made her first connection. She remembers T-Ray saying how crazy Lily's mother was when it came to killing things, even bugs. Lily then asked May if she new her mother Deborah, and it turns out she did, she had stayed there. I think this is forshawdoing something big, possibly Lily coming clean with the truth? Maybe something else with May? Any other guesses?
