Yeah that, AND......what if he arrived at the friends house and Dylan WAS there having a great time? Uhm mm, wouldn't it seem kinda ......drastic......to go driving that distance over there just to say "ok, I thought you were here". I mean, wasn't he EXPECTING that Dylan would be there anyway?
--- Did the friend even HAVE a phone? Maybe he HAD to drive there if there was no phone.
--- Did he only go there at ER's insistence? If they spoke beforehand and she told MR that Dylan hadn't answered her calls or texts at all that day and MR told her Dylan "was at friends house" and to chill. Maybe she told him he better eyeball Dylan personally or she'd be calling law enforcement pronto.
>>>>>>>>> Maybe it was actually ER that raised the initial 'alert' about Dylan's absence, forcing MR's hand. <<<<<<<<<<
If that's what happened, it becomes apparent that Dylan could have ended up missing for several DAYS before he was reported missing, with MR claiming he thought Dylan was at a friend's house all that time.
