What to Do?

Mrguy's half brother and his extended family left the state, leaving behind family cremains. Somebody thought mrguy wanted his stepdad's ashes, not realizing that he wasn't his real dad. Mrguy's step-niece ended up holding them and she reached out last weekend. What to do?

She isn't related to the ashes and never met them when they were a person.

Mrguy isn't interested in them because his stepdad was a creepy dude who punched him.

We discussed many options, including tossing them in the trash and saluting the pail (my idea). But mrguy is a proper fellow and was torn between wanting to do the right thing for his stepdad and wanting nothing to do with this problem and feeling sorry for our step niece because she was stuck in the middle. I pointed out that, yes, mrguy could make a long drive down to pick up the ashes and maybe get a niche near his mom's, but that he only has so much time and energy in his current situation.

Step niece to the rescue. She mentioned her situation to a friend who has a friend with a boat. For $600 the friend will scatter the ashes in the bay. Mrguy and I paused for a sec because that's where we scattered the big guy, and we don't really want their particles to be mixed up, and that's also where *we* want to be scattered and we don't want any of our creepy dude on us. 

But we will be dead then, and whatever.
