Cabe was wrong. He just didn't know it yet.
Unbeknownst to him and Sly there was a unwelcome visitor creeping around upstairs, despite the additional security outside.
Walter was standing at his whiteboard in his room when Drew entered, and though he saw the cloth coming towards his face he was deep within the rabbit hole and did not register it. As the chloroform dragged him into unconsciousness Drew held onto him and brought his lips to Walter's ears and whispered "I never to thanked you for hiring Paige. I'd have never met Merrick otherwise- and OH the power he's given me"
Of course Walter did not hear him. Drew smirked crazily as he lifted him with one arm over his shoulder. Before he exited the room he unclipped a handheld transceiver from his belt and ensured it was at the frequency he'd been told to have it- 10.12 megahertz. "I've been told you're always listening" he spoke into it "if you want him you can have the Nerd, so long as you keep him locked away for good. But if you cross me you'll both end up missing- if you catch my drift". Five minutes had passed before Drew got a reply- by that point he no longer expected one.
"Fair enough terms. Meet me at Ponder Creek Farm. Walter will not be a problem for you again I assure you"
Far away a bearded bespectacled man laughed madly to himself "You're mine now." He muttered to himself "and no one will take you away from me again"
