I forgot to mention another special case: Lucille and G'raha have a strained relationship bc of the latter's admiration for her and the former's complicated relationship of being the WoL. G'raha is perhaps the only person that she gets awkward around lol but they do eventually get better post-EW

Minfilia is quite literally the first person Lucille ends up trusting and confiding in; the twins bring out her softer and teasing side due to them being younger
In the other Scions' case, she begins to fail putting on a facade due to the stress and events near the end of HW leading up to StB

Ended up becoming a lot more calmer and warmer after Lucille matched her energy and would defend her against people's snide comments about the chocobo... And they've gotten along since :]

Lucille really cherishes Enna bc she's the first companion she ends up having and something to protect!

Forgot to add that there's nothing explicitly drawn, it's just written out answers for a select few questions
