I think Mrs Lovett and Sweeney Todd wern't dating bt were seing each other wich are 2 completely different things lol x x x x x nd i think she was like a mum to toby she really cared about him until she was ready to let sweeney kill him in the final scene lol x x x x haha :P x x x x x bt she always said to sweeney "Dont you fink yuu shud leave the boy" so she obviously didnt want him to be hurt which shows she cared, ide love her as mii mum lol x x x x x x x x x x x x x x x

lol yeah, those ARE totally different things ;D
but I see your point(s) and agree.. And she woulda been a great mum, eh?

I think she would have been an amazing Mum if Sweeney wasn't there, because lets face it: she was prepared to kill Toby for Sweeney.
