“Here is the hardest hit of all, O'Malley," Harry said. "Here is the very worst thing I can do to you."He held out his hand, as if asking for a handshake. He was asking for a handshake.Conor responded almost automatically, putting out his own hand and shaking Harry's before he even thought about what he was doing.

And that we would get through it.” He put his elblows on his knees and rested his forehead on his hands. “That we’d figure it out. That you weren’t alone.” Stab.Twist.He was right. It was just that simple.”

“Lucas Delos,” he said, holding out his hand.“Don’t you hate this kid?” Jerry asked Helen candidly as he shook the offered hand.”
“You are the Chosen One?”“Of course I am,” said Harry calmly.“But then . . . my dear boy . . . you’re asking a great deal . . .you’re asking me, in fact, to aid you in your attempt to destroy —”“You don’t want to get rid of the wizard who killed Lily Evans?”“Harry, Harry, of course I do, but —”“You’re scared he’ll find out you helped me?”Slughorn said nothing; he looked terrified.“Be brave like my mother, Professor. . . .”
