Cultural Tip
In French, "et si" is a very natural way to raise a hypothetical scenario in conversation. It works in both formal and informal settings, but in very formal written French you might prefer "au cas où" or "dans l'éventualité où". Also, note that the verb stays in the present indicative after "et si" because the speaker treats the situation as a realistic possibility, not a doubtful wish.
