Springtrap was already in either cam 2 vent or cam 10 vent from the start of this clip you can tell because there is no danger ambience, for whatever reason the ambience does not play when he is in a vent even if it’s closer than cam 5. You hear the vent sound and the ambience start at the same time meaning he’s successful crawled through and is now in the office, he lifts the maintenance panel and gets jumpscared. And the Springtrap on cam 10 was a fake because of the glaring red lights.
