He's not signing now -- he likes holding Galahad's hand too much to let go in service of continuing the lessons, and he squeezes Galahad's hand as a kind of signal to this effect. "When you and L.. Binghe... more than kissed. Did he tell you how he feels? About you?" This is the part of the equation Magnus is least clear on, but he knows that if Luo Binghe likes Shen Qingqiu, he probably won't hate what he looks like.
