I understand, when I remember, how to use ‘au cas où’. 

However, why can’t you use ‘il me faudrait’ after it, rather than ‘je devrais’. Both are in the conditional tense, and both mean (I think) ‘I must’. 

Anyone know please?

Here’s the relevant question, a translation of ‘in case I have to go out again’,  which was marked as wrong:  au cas où il me faudrait ressortir

In this lesson you say "Use qui when the following word is a verb or reflexive pronoun (e.g. me, te, se, lui, le, la, nous, vous, leur, les, etc)", but isn't there a mistake here? Can lui, le, la, leur be reflexive pronouns?
