In the webcomic Wilde Life, we're given some hints about the protagonist's backstory, but I'm having some trouble assembling them.
There's this three-page recollection where Oscar tells us he had a quiet, polite breakup with his fiance: http://www.wildelifecomic.com/comic/471
Then there's this flashback full of more alarming images: a wedding, an IV, an angry person shouting, a... a dog? http://www.wildelifecomic.com/comic/495
In the next page, someone says: "No! Dad, it's your fault" but it's hard to identify who or why: http://www.wildelifecomic.com/comic/496
What can we conclude about Oscar's backstory?
