kinda funny the better parts of this ep were filler. they did a good job tying it in tho, you cant even tell unless you read the manga.

ibikis summons, the 2nd attempt to kill the dog thing with the biscuit-firing, and the summoning inside ibiki were all filler.

only problem i had with any of that was ibiki didn't take anywhere near the damage you would expect someone to take if they had a giant bird summoned inside them. he wasn't even unconscious.
