OH how neat it is to have a Sonic that is so hellbent on redemption due to the fact that there was one person he could not save (because he wasn’t allowed to) and doing everything in his power and mind to correct that “failure” to the point of ignoring his own personal boundaries and values and how neat it is that Shadow has gone so long without such simple pleasures of having someone seep into those stony walls built up on sandy foundations so he allows this if only to center him for just a little while, to remind him that he is someone, not something.
and how delicious it is to have someone fall in unfortunate love while the other is already too taken with themselves and their stubborn ideals to notice (or maybe even to care,,,)
also the gag of it all being that they still act just as their usual selves the entire time, maybe with only glances of it shown to those who know them best--
