I love Spreaver so much, literally because even from the games the two looked like they absolutely loved pissing eachother off.
Here's my list starting with Sparrow's side of things:
- Usurped Reaver
- Became royalty which probably saved them from getting killed for it
- Has the last Dragonstomper.48 gun for Reaver's collection locked in a 50 silver key chest in the gardens
- Literally KEEPs Reaver's dark seal, like doesn't he need that? Literally asking for him to come back
Now for Reaver:
- Got a home for himself at Bowerlake, spoilt nature from it
- Not to mention it blocks the way to Hero Hill and to the tomb, both of which are pretty significant to Sparrow methinks
- He kicked out the Romani (ofc Sparrow's family essentially) from their dwelling grounds
- Literally all his interactions with Sparrow is just fucking with them
They love-hated eachother and you can't convince me otherwise. This is just generalised from the games btw so really it works for so many Sparrows, love or hate or both.
I might be missing some things but this has been haunting my brain for so long.
ADDING TO THIS
I realised that there's another reason to why Reaver probably didn't kill Sparrow for usurping - it's because, even though usurping is one reason to kill them, the fact Sparrow would have known about his past after reading his diary pages is another reason, because why on earth would he want that to spill?
The simple answer: Sparrow can't spill about it, it's either not in their interest or it's really down to the fact they're mute and can't say a thing about it! Of course becoming royalty just adds to Sparrow's protection against Reaver so now they're just bitter sods to eachother.
I imagine Reaver isn't the kind of person to let anyone know of his real past and how he was once a caring man. It just taints his image and makes him seem softer, can't have that ruining his persona.
Luckily Sparrow's the perfect person to keep their mouth shut about it.
