Yeah maybe don't commit incest at your parents house if you don't want to get caught for incest. I guess they didn't like their parents anyways so it won't matter to them if they never talk again though.
Didn't they say they're in college though? Sure there will be drama but they're not underage anymore, won't be easy but they're free to do whatever they want now
