Raisa was in employment by the Queen family in 2007. She once collected Oliver from Tommy Merlyn's house with a four month old Thea in a stroller, which was the first time Malcolm Merlyn saw his daughter. 
Raisa later brought him a meal, and when asked by Oliver if he seemed different to her, she told that he didn't, as he was still a good boy. Although Oliver said that they both knew that he wasn't in the past, Raisa told him that he had a good heart, to which Oliver responded that he hoped so, because he wanted to be the person she always told him he could be.
Taking care of William
Raisa is a kind-hearted woman, who always believed Oliver had a good heart even though his behavior wasn't the best before being shipwrecked.
