You do not use 'in case' or 'just in case' to express that a little something will come about on account of something else happening. You don't say, by way of example, 'I'll go in case he asks me'. You say 'I will go if he asks me'. Writing: Now, https://cesarkxnsl.tokka-blog.com/36570238/helping-the-others-realize-the-advantages-of-case-solution
