Realizing that there was no way for her to get away from Dominic and Hestia (and likely that she wouldn't want to get away from them,) Ernie went closer himself. With Hestia and Dominic clutching her so tightly, he could only reach for Hannah's hands, but reach he did. He took one of them in each of his larger hands and squeezed them tightly--though he was careful that it wasn't tight enough to injure her. He realized that even had he had the opportunity to do so, he might not have hugged her right away for fear of harming her. Lestrange could never corrupt her to the point of wanting his romantic advances, but he was larger, and blessed with magic in tough situations when Hannah's magic became almost nonexistent. He could have forced himself on her, and Ernie didn't want to do anything that would further harm her.
"I missed you so much." He swallowed deeply, not liking the rough sound of his own voice. "I tried everything I could think of to get you home. Welcome back."
