'Tom' nodded; yes he did remember Wanda mentioning the boy, but she hadn't gone any further, so he didn't want to pry, despite his curiosity. The more Loki knew, the more he could use against her in his plot to break her down.
"Billy?" The name made him pause. His disciple was named Billy. Could it be the same person? Without Wanda knowing, he cast a spell and was able to see the connection between Wanda and the young man Loki had named Wiccan.
Loki wanted to laugh, but instead he set down his fork and leaned forward, placing his hand upon Wanda's. "What are you trying to say, Wanda? That you believe this 'Billy' is your son?" There was nothing but concern upon his face. "But how can that be? You know that your sons... I mean... well. They died when they were two. You've just been thinking about them more often than usual, and especially on a day like today."
