I've been thinking about how in the 1940s Crowley cannot walk into a church without it being physically painful due to it being consecrated/holy ground, however flash forward to when he goes to heaven (either time, really) we don't see him be in that same type of pain, even though objectively its more of a holy place than any church.
This could be just a property of heaven, or a writing inconsistenty, but it makes me wonder if Crowley is in pain in these moments, but the situation requires his comfort to be an afterthought. Or potentially its desentization, hes been on consecrated ground many times since saving Aziraphale in the church for whatever reason and he's used to walking on it.
