After Diego was done with Tara, she was bleeding all over her body. But the worst pain came from her ribs. Diego has lost it so much that he beat her up, like a thief who stole something important from him.
But she's no different from a thief, she took his child away from him and he wasn't joking when he said that she was going to pay for what she had done to him.
His initial plan was to kill her there with Tom, but he figured out that it's too easy. That gives her a painless death, she doesn't deserve that.
"Ple..please, he..lp." Tara mumbled, which made Diego snickered at her comment. Even at her last moment, she still thinks that someone is going to save her.
He abducted her to his uncle's safe house that was far from the city, although this wasn't included in his plan with his uncle but this was his very own vendetta. Afterall, they were working on the same page to punish those who had wrongfully accused his mother.
