Considering the variety of sexualities among his friends, Justin should be aware that attraction towards one woman implies very little. At best, it could be taken as implication that Luke might be straight, heteroflexible, bi, pan or homoflexible. I know Justin is clueless enough to be unable to tell that Luke was scared of Grace hurting him, but he should know that much!
