   If we have a present or future tense in the main clause, we use a present tense after in case; if we have a past tense, in case is followed by a past tense. In case + a subject + should + infinitive is another alternative to in case + a subject + a present or past tense, but it suggests a smaller possibility. As regards lest, it is followed by should or by a subjunctive8, and is very formal.

a  I'll leave him a message in the answering machine because he might go home this afternoon.
b  He wanted to kiss her, but he did not, as he thought that she could reject him.
