Suguha and Inoda, Inoda and Suguha, fuck or not to fuck that is the question

.
If we use a "bird's-eye view" in the Fujino's story or any story for that matter we always will see basic the same things, motivation, interactions and actions the basic stuff for any plot.
The main argument/reason for the people who are against, is the lack of previous interactions between them, which is true for direct interactions save a couple of times and they never even had one single dialogue so it's a fair logic.
But indirect interactions not so much, their individual plots are tied togheter, Inoda motivation and actions in the story had enabled and fuelled Sugu's actions and motivation. Because of that the lack of interaction is not a problem without solution, in the end they share a similar motivation.
If Fujino didn't had any intention to make this (sex) happen in any way shape or form, he woundn't make Sugu aware about Asuna's affair (Inoda actions) which will led in the future to a inevitable "confrontation" between the characters (direct interaction). And with the Liz rape as plot device he made Inoda aware about Sugu's actions and motivation which put Inoda in a position of advantage for this future interaction,
That means Fujino will do it, i'm not so sure probably no, but that depends on him, and he's being vague about it the only thing he said was "he will try something, but the things may not go or be as he expect" so, vague.
Maybe Fujino will use this for something that is long overdue, Inoda getting reckt for a change which will be fun
In the end, Fujino left some pretext in order to create context.
