Perhaps the real reason why Lotus said no was actually because she knew (obviously) how much of a gossip Rarity is, and is actually trying to do him a favour of preventing his “secret” from getting out, should Rarity find out. On a another note, I am intrigued as to find out how this Tumblr series/arc will conclude.
Well yes, but I do believe that Lotus wasn’t ever made aware of that.
