I think Forest may stay up.
Southampton are down
Will be whoever gets to 36 points or more with best goal difference.
Us, Leicester, Leeds and West Ham - I reckon will be 2 of this 4, with us in the worse position, needing results, with at least 2 wins, against Leicester, Wolves and Bournemouth to be sure.
Get beat Monday and we have to get 6 points from those last 2 and hope.
Win on Monday and we need 4 points from all remaining.
Big Ask.
Not one of your scenarios has us on 36 points which you say is enough.
