Sister Complex (3.5e Flaw)
From D&D Wiki
 Sister/Brother Complex
You have feelings for a sibling.
Prerequisite: Character must have a sibling.
Effect: When you are near or around your sister/brother you do your best to show off. When they are near you receive a +2 moral bonus to your reflex and attack rolls, but must make Will saves at -2 to prevent showing off and potentially endangering yourself or others. When she/he isn't around though, you seem to be distracted thinking about her/him and suffer a -2 penalty on your reflex and attack rolls, although the Will penalty is removed.
