There's also quite a bit of battle potential between Lyon and Gray in this situation.

Lyon will want to fight this Ur one-on-one, even if he knows it's not the real Ur. Her being exactly like Ur and having similar power is good enough for him to proof that he surpassed her.

And Gray might be unwilling to let that fight happen and try to break it up, which in extreme cases may even lead to the two coming to blows with each other. Probably unlikely, but possible.
