[Grammar] Usage of "Lest...Should" and "In case".

[shahjehansoomro]

Are the following sentences same according to English grammar rules and meaning?

# I remained in the hotel up to 4 p.m lest he should come there.
or
# I remained in the hotel up to 4 p.m in case he came there.

 

[Tdol]

The second makes sense.

 

[MikeNewYork]

I agree with Tdol. The first makes no sense because "lest" means "for fear that". Why would someone stay if he/she were afraid?
