While I have no illusions that TO will become the permanent HC, it would not surprise me if he, indeed, leads the team onto the field one more time.
The man is older and certainly has higher priorities (family) than the Husker program. TO never showed his emotions, as I recall, in trying times in the past. Most or all of our posters remember the 1990's NC years, but there were some lean times, as NU football goes, earlier in TO's HCing career. The late 70's were tougher times and some near-miss NC in the 1980's had to be quite disappointing. TO probably had pressure and doubters in trying to measure up to the Bobfather.
TO, and maybe Nancy, are the only ones who know what TO is thinking right now.
If TO played poker, which I sincerely doubt, he would be one of the toughest reads out there.
BC better get his ship in shape and fast. BC will make some changes, if nothing else something to get the players enthused, and there will be only two people in on these discussions. If BC is smart, he will ask for TO's input. While I have been deeply critical of BC, maybe he just needs some guidance, but I truly think BC is a lost cause.
