No one spoke, what had Ron expected? He hadn't left his room in days. He was barely eating and honestly it was all for good reason. Hermione knew that Theo was hurting but at least Luna was alive. Fred had died to save her and Ron would never see his brother again, he couldn't even go to the funeral for fear of not being able to find them on return, or being captured. Lupin was the only one who knew where they were and he passed on messages as best he could up until he left. They were trying to give Ron what he needed, he wasn't in any shape to be flying around Hogwarts searching out giant snake fangs.
