Luke waves around Anakin’s lightsaber like a toy. Rey holds it like it might break her. That says everything about them.
Luke just flicking the switch and going "cool," while Rey acts like she's handling a holy relic.
He turns it on waves it around like a kid with a flashlight. No reverence. No hesitation. He's feeling the weight in his hand but not the Force. He's just... playing with it.
Then cut to TFA. Rey touches the saber for the first time and the whole movie stops. The force vision hits her hard. She pulls back like it burned her. When she finally holds it, there's this overt almost religious caution.
