I took from Krista's testimony was that Nancy was tired of painting when it was obvious it wasn't going to be the benefit she thought it would be. When she thought she was going to receive EXTRA money for it, it was worth it. When Brad deducted the money from her allowance, it wasn't that much worth it anymore. IF - and this is a really big if - IF I were to think JA lied about anything it would be that she lied to say she would do exchange work to organize when in reality she was going to pay Nancy all along. I think that IF there's a lie there, it is that she and Nancy cooked up the exchange story and JA was secretly to pay Nancy instead. Remember how Krista testified that when she wanted to give money to Nancy that Nancy begged her not to and said "you get to leave and I don't - I have to stay here, and have to deal with the repercussions" - or words to that effect. I could see lying about the exchange for work just so that Brad would not deduct money from Nancy's allowance.
