Harry takes this time to open his backpack while walking and extract a roll of tape. While continuing to walk, he's going to attempt to keep away from zombies while force-taping his scissors into the open position. The length of the space between two eyes. Tweaking, tweaking, more tweaking. Fast tweaking, while he half-listens to you guys.
Testing time to see if that works. Just outright stabbing the first one of these things that tries to bite. In the eyes, twice and then through the sinuses.
Yeah. That works. And is kind of gross. Ew. Needs more tweaking.
