Who wins this lawsuit, Ron or Lana?

Lana said she was divorced, so that Ron would hook up with her on fri. night. Sunday morning, Ron walks into church, and sees Lana with.. her husband! Lana pulls Ron aside and offers him a check for $900 (Made up to her by her brother Jim) to never tell, and they write up a contract. She properlyendorses it to Ron. Jim lives in the same town as Ron, so Ron goes to JIm's bank to present the check, expecting to have it credited by 5 p.m. Luckily Jim's wife Martha is there to deposit a money order from Lana's brother Charles. She deposits it and buys a $800 teller's check and $100 to give to Ron, in exchange for the $900 check. (Else that check would have bounced.) Ron calls a taxi, to rush to his bank and is thinking caching! Lana, however causes trouble, by calling martha up and claim that Jim's signature was forged, then claiming hers was forged. Ron has made it to the bank, and has put in the cashier's check. (He gave $100 to the cabbie). Lana tries to have the $800 taken out of Ron's account. She went to lunch with hubby, and Ron's twin Rita, across from Ron's bank. She goes to the bank and claims Ron forged. Rita says "Ron can't forge HIS OWN signature!" Ron called Rita to warn her of Lana's trickery, because he knew Rita would overhear Lana's claims, as she and Rita were spending the day together. Ron's account is credited immediately after the bank showdown, and because of all of the hle Lana gave him, Ron, after having the dough, rats out Lana to her hubby. Divorced, and now without alimony, Lana sues Ron for $900. Who wins?
