SPOILERS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!


well in the manga the piece of the mask the hollow wears wasn't restored so it was still broken off
ichigo and the hollow didn't fight outside, the hollow was facing off against him in the house then attacked orihime and practically the same scene was displayed with orihime jumping inside her brothers mouth
the hollows mask didn't explode into pieces it broke down and fell to the floor
ichigo was still holding the sword in his hand when the hollow grabbed for it to stab himself with it, so no big things were changed they probably just made it a little more exciting with the hollow slamming ichigo out of the house and then chasing after him which he didn't do in the manga cuz ichigo jumped back up into the house

so only minor things were changed but the intergrity of the manga was kept in tact they changed much more in the first 2 eps then this one, a lot of jokes were left out or were more funny in the manga

SPOILERS END!!!!!!!!!!!!!!!!!!!!!!!
