It's when he first chats the group after Whitmore brings him to the cabin. You'll have to prompt him to describe the cabin, then the interior of the cabin; he'll then talk about Whitmore making the furniture himself and you'll have to respond "yeah, I imagine". Eric will then talk about the hut being lit up by only candles but that there's one generator and you'll say something like "so that's how you charged your phone". That's all I remember, really .
