As charming as it had been to see Galen find it in himself to see Lucario not as a pet but his companion that moment was all too brief before he was worried about his master and whatever punishment he might earn having been pulled into this world.
"He's not going to find you," She said, without correcting him about his name, if he wanted to be called Starkiller for now he could be, it was far more important to her that she got Galen calmed down than to make him answer to a name that still felt wrong at this point in his life. "He's not going to find you and he's not going to hurt you, I promise." She assured him, moving forward even as Galen staggered back before falling to the ground.
Barbara knelt then as he looked up at her. "It's okay, I promise." She told him gently, "No one is going to hurt you here. I won't let them." And she meant that too, she wouldn't allow any harm to come to Galen here, and most especially while he was like this, still young and scared. "We're all stuck here." She reminded him, or told him for the first time, depending on how you looked at it. "But that means your master can't find you here too." She added just to soften the blow of his finding out that he was stuck here.
