Re: NATASHA.
Loki never purposefully ignored Evil Natasha, but he usually kept his distance because they ran two entirely different packs back home. (Ones that only got along at the moment in order to complete their current mission.) He did, however, pay close attention to Good Natasha because she seemed much friendlier than her counterpart. He found that curious. And when she finished her song he gave her a few slow claps.
