In the activity "En attendant Aline (Le Futur Antérieur)"

It's two in the morning, she must have had an accident! Il est deux heures du matin, elle aura eu un accident ! 

As per my understanding, Futur Anterieur is used for "past" (anterior) events in the future. In this context, there is no future.. They are discussing the possibilities in the past. Could someone else explain. I went through the lessons on Futur Anterieur and did the quizzes. I was able to understand clearly. But this particular activity, I could not understand. Please help.

In the sentence ' As I grew up, it was her melancholy ...' the advice is to use c'est. Why not c'était?

and,

In the sentence 'Barbara, as you used to sing (it) so perfectly, our most beautiful love story will always be you., the 'it' refers to the 'love story' which is feminine so 'comme tu le chantais' should be 'la'?

Thanks

Why is it, "Elle a monté les escaliers..." and not "Elle est montée les escaliers"?

When you keep your normal statement followed by quoi at the end

Can you replace it with comment 

-Tu fais comment?
