I generally agree there's likely to be such angle there, but the one thing that made me somewhat wary regarding their interaction was how Ian can declare he'd do everything for success. It feels very much like "contract with a devil" sort of a deal, and it won't surprise me in the least if part of that "everything" included bringing Lena who refuses to work with Seymour but is Ian's girlfriend to Seymour's heel.Whether or not Seymour has is passing his wealth, power to Ian, he is going to take Ian under his wing it's just a matter of time.
(that and how Seymour keeps making evil faces when he's having these benevolent interactions, ofc
