After her last encounter with Amelia at the food Mart, which left has shattered for days, Tina swore to make Amelia pay for all her heartache. She secretly reached out to Amelia's aunt, Pearl, using the affection of a con artist.
Through this con artist dating Pearl, Tina was able to dig into Amelia's past life and a little bit of her present life. She discovered that Blaze was never a part of Amelia's life until after the unsuccessful assassination attempt.
This discovery supported her theory that Blaze and Amelia were never lovers when they became man and wife. It explained the reason behind their secret marriage. It simply meant their marriage could be based on a contract since the two were never friends in the first place. And knowing Blaze very well, Tina knew there would be stringent conditions to the contract.
All she had to do was find out what these conditions were and make sure Amelia broke them. When that happens, she would take her man back.
