Just emphasizing on Nick's point 1> "Loke didn't ask/ demand her to break his key". Yep. You see, Lucy doesn't go breaking keys anyways, she wouldn't be like: "Oh, Sagittarius is more useless/ weak let's break his key". It's because Aquarius agreed/ demanded to it. As for the Loke thing, Loke doesn't summon himself out of nowhere, he summons himself to his key. So if the key is broken he can't summon himself to it (same goes for Lucy on summoning him), oh and the contract would be broken too, so Lucy wouldn't be Loke's owner.
