is bleach episode 2 filler?

The morning after the fateful battle against Fishbone D, Isshin Kurosaki crashes feet-first into a sleeping Ichigo Kurosaki while greeting him, only for Ichigo to scream in anger before pinning his father to the ground while berating him for attacking his own son in his sleep, which leads Isshin to compliment Ichigo's skill and declare that he has nothing more to teach his son. Ichigo suddenly remembers what happened to his family and the house during the previous night and hoists Isshin up by his collar before frantically asking him about Karin Kurosaki and Yuzu Kurosaki's injuries, only for a confused Isshin to wonder what he is talking about, which surprises Ichigo.
