cameron siblings

i know this show isn’t realistic on realism, but the relationship between them is unrealistic. wheezie doesn’t like rose and there is no reason why she wouldn’t be fighting to see her siblings especially sarah. rafe kinda made sense until s4 on not fighting to see her. sarah doesn’t make sense, she literally risked her life million of times yet wouldn’t for her sister?? there’s no way she can live happily without some guilt or being some kind of upset about not being able to see her sister. they could’ve atleast showed her feeling upset or talking about her more.
