Setting her plate on her opposite side, she scootches up to her brother.  "Hey.. Brian.  It'll be alright.  Whatever it is that's wrong... it'll work out.  You and I can make it through together.  We always have..."  Wrapping her arms around him, she gives him a brief hug, then ruffles his hair in that way that always annoys him.  "You can't get rid of me this easily...  Even if you run off, I'll track you down and make you eat my horrible cooking!"  She's purposely being silly, trying to lighten his mood, but the pain he seems to be feeling makes her troubled.
