Uhm... if the boy really has these psychological traits, that’s not how to cope with it - by sending him away or belittle his every doing... he probably got told multiple times that he should be more like his brother or that he isn’t as good as his brother. Or he didn’t get as much attention as Nick so he developed those unhealthy mental issues.
Louis is definitely my favorite, no wonder he's our MC >u< (I mean, he can be petty and nasty at times, but so far I think he's a good man, also as an adult who has a messed up life and never has enough energy I can relate)
