ACTUALLY if you're up for it and wanted rosi to see wash's death, i have an idea!!!

wash could be stubbornly camping out without realizing he's got a second grave (since he destroyed the first one and they multiply on respawn) and rosi can make an offering to that one, have happy death funtimes, then encounter wash at the original site and inform him that uh you've got another one bro. at which point he'll realize camping out isn't going to help much and they can talk and maybe he'll go make some more offerings of his own?
