If she'd been watching the pair she might have noticed, but as it stands she was purposely trying to grant them privacy.  So she continues looking over the new things until Brian moves the generator to the window and starts it up.<br/><br/>Liz plugs her ears against the noise.  Shouting over it, she asks "What if we put them outside?  Then we could run a cord or something from them and in through the window!"  She can't help but smile.  Her brother has always chosen different solutions than most people do.  Sometimes it works out well, other times... not so much.<br/>
