Get an icepack.

You ask her where the freezer is and get some ice.

"Here." You put the icepack on her shin.

She sits on the couch silently.

"R-Really...I can--"

"HEY!"

You turn around quickly to see who said that.

"What did you do to my daughter?" a man who is obviously her dad says.

"N-No, Dad!" she says, trying to keep him back.

"Err... Uhh... Sir! I was just--"

"Are you okay, Emily? Do you need to rest?" her dad interrupts.

"No, I don't, he was just helping me!" Emily shouts angrily.

"He isn't your boyfriend, is he?" her dad whispers. "I mean, he is pretty go--"

"Shut up!" Emily screams.

"Well, you seem like a nice guy," her dad says. "I'm George." He reaches out his hand.

You shake it.

"You can stay here and help her," George says as he walks up stairs. "But DON'T do anything stupid!"
