Tach tilted her head, glancing around the immediate area. She didn't see him. He couldn't have gone too far, though. She skated up the sidewalk a bit, poking her head into an alley to check there. Nope, though there were some pigeons. Walt couldn't turn into a pigeon, not that she knew of, at least.
She scanned the crowd again, then spun around to check behind a mailbox. Nope. He wasn't crouched between the newspaper boxes, either. She peeked behind vendors and glanced through a few windows of shops. She glanced up to see if maybe he'd scaled the wall. Tachikoma was very determined. After a bit, she started poking her head inside stores to search them more thoroughly.
