when he gave that kid his car and sat on that bench in the middle of nowhere waiting for a bus to i dunno where w/nothing on him i figured it's a great time for him to start over.

he has no connections to anything - oh, i guess he owns a condo in NYC, maybe. but otherwise he has no job, no marriage, no ongoing spousal-support obligation (Megan took a cash payout which i assume came w/o further obligation), no ongoing child-support obligation (b/c Betty has custody and she's married). he has no extended family (Anna Draper is dead and Dick Whitmore's brother is dead). as long as he can access that Don Draper savings account at whatever bank is holding his money he's all good. he can become anyone. he doesn't have to be Don Draper anymore. i wonder if he'll continue w/that identity.
