Why did Natalie get rid of the items?

"What else do you know about Natalie?"

The ring was given to Natalie Steel 3 years ago.
The ring was given to Natalie by Snow.
She kept the ring in hopes he would one day return.
She threw away the ring when she found out he was part of the Scarlet Seal.

It has been two years since the death of Natalie Steel. There have been reports of Nikita and Paul being seen in England, France, and Ukraine... Despite your best efforts, the leads never resulted in their capture...

Natalie went to Hong Kong to find her missing brother. Unable to stop thinking about the case and Natalie Steel, you decide to venture to Hong Kong. If you can't investigate the Volkovs, at least you can try to find Natalie's brother in Hong Kong. Maybe this will put an end to your nightmares...
