New voice lines in Fortnite hint at Season 5 ending with an event involving the Zero Point. Multiple non-playable characters have received new voice lines, most of which refer to an ominous threat. A Reddit user posted a screenshot in which Deadfire states, "Mysterious things have been happening 'round these parts."
Deadfire is not the only NPC to warn players about "mysterious things." Mancake points out, "Was that thing always so... unstable?" And when approached, Bunker Jonesy tells the player, "Here it comes, don't say I didn't warn you." As to what the "it" is exactly, no one knows so far, although there is a lot of speculation that it is referring to the Zero Point.
The Zero Point has been a subject of many theories surrounding the end of Season Five, particularly with a tweet from the official Fortnite page dating back to Dec. 2, 2020. It featured a cinematic where Jones tries to stabilize the Zero Point and reseal the bridge, but the Zero Point ended up being exposed. This event may be what Mancake refers to as "unstable," but this is mostly speculation amongst the player base.
Fortnite Chapter 2 Season 5 ends on March 15, 2021, so Epic Games has less than a month to officially reveal what the finale event will be like.
