LLOYD, YOU CAN'T BACKLASH WAVE A BACKLASH WAVE!!!
kudos if you get the joke

I'm tried of everyone saying Inu and Sessy's dad favored Inuyasha more....HE DIDN'T. For god's sake Inuyasha was a baby (pup) when (or rather right before) he died, while Sesshoumaru was a fully functional adult (or mature teenager) not to mention Inu was a half-breed meaning that he was at even more of are risk. Inu got the more powerful weapon so that he could take care of himself, Sessy got little to nothing because his father knew that he could take care of himself and if nothing else Sessy has the talent and smarts to probably surpass his father one day in his own way (with out the help of daddy's weapons). And the reason Inu and Sessy keep on crossing paths is probably because the father wanted them get along (or at least tolerate each other, enough not to kill themselves).
