I'd love the wife angle too, that'd bookend that part. Leave Henry as a mystery, I personally think he was a stooge, using Linda and Mei as bait to get the boat when someone suitable 'passed the test' of taking care of Mei and helping a 'wheelchair' user. Would like to think that, if they did include Henry, he sets out to find the Hero's wife, and she goes looking for him after finding out he set up her husband?
Wow, possible 2 more games there then:
1) Hero goes looking for Henry; records fact he's a stooge on the camcorder, stashes camcorder where he knows wife'll find it.
2) Wife goes after Henry.
There. That's better. As I wrote that, I formed those ideas as a better story arch
