It's why I posted it. The dog is so sweet and loyal, he supports his master's dream. Only, he's so innocent, that he doesn't understand that his master is committing suicide (and that his previous attempt failed). So, he's gonna be all happy and chipper when people find him (after finding his dead master). Either that, or no one will find him before he starves to death, and so he'll die along with his master...but he'll die happy.
“…Judge not what a man has done, but judge what he could have done if he was a different bloke altogether. For art thou a leper? And a leper can changeth his spots…” --Rudy Wade, Misfits (Series 4, Episode 8)
