What I'm saying if, just because the House you are is known for being meek doesn't mean you have to be meek unless you allow it. Human will can overcome a lot of weaknesses if they want it badly enough and even with evolution or...whatever might have happened, that seems to be a rather strong trait regardless.
...might be I didn't need to say anything, but I remember how Romans are and they were kind of crazy about some of their pedigree stuff, just...wanted to say something in case you thought you had to be your House.
