When Ella and Marina become friends, Victoria gets jealous. She keeps on threatening Marina to stay away, and if Marina tells Ella, she will claim it's not true, and Ella still trusts Victoria.

Later on, Ella tells Victoria that she is not "betraying" her and doesn't know how she would be. Victoria tells Ella they were were friends first, and that Marina "doesn't seem trustworthy." Ella doesn't care, and keeps on being friends with Marina.
