Wickham will Marry Lydia if...

Mr. Gardiner found Lydia and Wickham, and he agrees to marry Lydia for a relatively small amount of money from the Bennets; however, the Bennet's assume the Gardiners paid Wickham a large amount of money to agree to the marriage. This would mean the Bennet's would owe them money. The Bennet's don't know this yet, but I was the one who paid Wickham, and I do not expect anything in return.
