he showed her the numbers on his chest in order to prove that he also has a power, so how come the numbers on her chest were never mentioned once by either of them while he was lending her a helping hand and her chest was exposed? i mean he already knows and thats why he might have not asked on purpose but what about the 1st time it happened? before he get his power and learn of hers? or shouldnt she at least wonder why he doesnt ask? or keep it covered from him so he wont suspect something?
