Saint's Links
Saint remembers Vladim in her past life. Knowing he is a very dangerous and faulty synth with unnatural strength and defense, she chooses not to go near him. She is fearful of him as she has heard rumors of him being one of the most gruesome fighters there are.
Vladim remembers Saint as a synth, but as well as the scientist, Ximena. He has a deep hatred for those in the institute and doesn't acknowledge Saint is Saint. He believes it's Ximena and believes she is out to get him. He is prepared to fight for his freedom, but also to take revenge on her for taking his whole life away by making him a "disgusting synth".
Saint doesn't like Ella, due to the fact she is the Director in the Institute. However is thankful for the fact she is so focused on Vicente, that Saint is able to get away and knows Ella won't waste resources on her.
Ella is aware of Saint's existence, but as long as she stays away from Vicente and her, she couldn't make herself care where the synth goes.
Saint knows a little about Vicente. She remembers seeing him in the institute, but never really took an interest to interact with him. So she doesn't know enough to form an opinion.
She also knows his secret between Ella and him, but doesn't care enough to say anything.
Vicente knows of Saint due to her status in Nukaworld. He finds her to be part of the problem of the world. If given the chance, he would take her out.
