From what you are saying I would expect the original loan to be deemed dischargeable. You may be able to convince the court that you have proof of fraud through whatever is contained in the answer to the complaint - I wouldn't want to guess without having seen it. It would be even better if he admitted to a fraud on the record, and you can produce a transcript.
The bad check should not be dischargeable.
You can file a motion with the bankruptcy court to try to reopen the case to revisit the issue of your debts. I would suggest getting a lawyer's help to draft the motion, as it will improve the odds of its success. Also a lawyer will be able to advise you as to how factors not yet discussed in this thread will affect your chances, such as the amount of time which has passed since discharge.
