Instead of the "make it so" reference to Picard, I came up with a different angle:

In part 2 of Picard Becomes a Borg (not the actual title), Riker realizes if he does things the way Picard would do them, Picard will easily counter him, AND there's a TV advert where everyone running a business, from small to large, asks, "What would ?? do", with the ?? being some other named company.

Combine these two together and everytime Sejanus looks like he's thinking I called out, "What would Riker do?"
