|I didn't really like Prue. She always came across a bit umsympathetic(eg. All Hell Breaks Loose when she shouted at Leo. The man's wife just died!) But Phoebe was much nicer.|
Prue was nice to Leo, too. Prue was just upset about losing her baby sister, who had died in her arms. That was devestating.
In the episode "Pardon My Past" Prue invited Leo to the party because she felt bad because Leo was lonely and had no friends.
In the episode "The Honeymoon Is Over" when Phoebe goes off on Leo when he took Piper to visit the Elders, it was Prue who told her to lay off because she said that poor Leo looked beaten up already and didn't need anymore beating on from Phoebe.
In the episode "Awakened," Phoebe rolled her eyes at Leo when he couldn't help, but Prue was more understanding towards him.
In "Astral Monkey," Phoebe was annoyed with Leo eating the cereal, orbing in and out, and when Prue asked her where was Leo, Phoebe replied, "In the the kitchen with Leo......again!" Phoebe even said that Leo was the big brother she never wanted. Prue had no problem with Leo moving in.
