Channeling James Allen (?), It appears that Mark did, indeed, retrieve his smart phone from Professor Bee Sharp in one of those “assumed” actions left unseen, before leaving Rob’s party. I don’t know why Mark needs to “try” to get into Rob’s place, as it seems clear Cricket Bro expected Mark’s call in the first place. Of course, as the villain, Cricket Bro is made to indulge in deliberately annoying jargon that only riles Mark even more.
But who is playing whom? The presence of Professor Bee in Cricket Bro’s office suggests that “Robbie Boy” (a put-down that Mark apparently didn’t think of when he was a kid) is already formulating his own plan of action, based on too many nights watching Wrestlemania.
