What in my brother's chart makes him a , yet, so sweet and cuddly?

Well, when exactly is his birthday and how old is he? BTW the pillow thing and saying come to papa seems like he's thinking of "something" so that just might be boys being boys, but from the mean side he sounds like a scorpio or a capicorn, but from the sweet side he sounds like a libra aquarius but he might very well be a leo as the hardness, leo's are usually good at hiding their feelings. So are Libras and Libra's can sometimes have a well.. double personality but not in the medical terminology, he's either a Libra, Leo, or a Scorpio. That's just my geuss I mean Horoscopes and Astrology aren't my strong suit.
