It is a little known or acknowledged fact that for every alternate timeline, there is in fact, an alternate W.D. Gaster that inhabits that timeline. Or rather, inhabited. However, Gasters in the Void cannot perceive each other, only Gasters that were not erased in their respective timelines. One major reason for this is the gray rooms. The gray rooms are where most Gasters are found. They are pockets of existence latched onto the timelines of the Gasters that inhabit them, but not directly inside the timelines and therefor not viewable by the other Gasters.
Every Gaster in the Void, such as the partially melted one currently peering intently at the back wall of his gray room, is able to perceive and view timelines, seeing as the Void was the space between them. In the words of this Gaster, it was almost like watching TV.
TV where you got to watch your friends and loved ones toyed with and/or murdered by either a benign or malevolent, space-time controlling anomaly.
But that was not what Gaster was looking at. He had pushed away from those 'shows' long ago. They were all extremely similar, regardless. No, what Gaster was looking at was something much, much different. It was a timeline the scientist couldn't access.
Ordinarily, he merely had to prod at one of the arching white lines on the wall to view what happened or was happening in that timeline, and the 'current' timeline was always outlined in red; presumably to symbolize the determination of the human within.
This time, however, the current timeline's vibrant red outline seemed to be washed out, with the primary white now an odd pinkish color. That alone was unsettling enough, as the only other time a timeline changed color was when the fallen child annihilated it, turning the line from bright white to pitch black.
Even so, there were two things that made this situation even more alarming. Firstly, the pink was starting to bleed past the red borders. Second, the timeline was starting to fracture, its ends splintering off. Now, this would be fascinating to the scientist if not for one thing: the splintering had already touched two other timelines, and it was gradually turning them pink. These changed timelines were getting unstable, and the scientist hypothesized that they would collapse entirely if not treated.
This was a virus.
Gaster's lone functioning, albeit lightless, eyesocket quickly took this information in, the ex-Royal Scientist's mind working to try to find a solution. Brilliant though he may be, Gaster could only find one solution: Walk into the timeline, and manually destroy the anomaly before its virus corrupted, fractured, and collapsed every other timeline. He had to contain this infection.
Gaster sighed. Just had to be only one way for everything, didn't it? Fine. He reached into his less-melted sleeve and pulled out his last resort. It wasn't very impressive, to say the least. A little tube, metal cap melted and fused to the glass, and sloshing with a thick, red liquid. A vial of Determination. Gaster sighed again. He had been saving this in case he ever found a way to return to his own timeline. To exist again. He wanted to see if any Alphys found a way to safely bring their Gaster back, or, failing that, if they found a way to safely inject DT into a monster.
But this was the fate of every timeline on the line here. He had to do it, no matter the risk. Besides, he already knew that door, which he had mainly just placed there to act as his hope for returning, occasionally appeared in Waterfall. That's how Frisk found him, after all. A Frisk, anyways. He was certain with enough Determination, that he could make it work.
Well, he wasn't certain. Not at all. But he had to at least try. Besides, he was partially melted already, what could a bit more do?
"❄ ✋💧 ✡ ❄✋ 📬" {There is only one option.}
"✋ ✌✞ 👍 ✋👍 📬" {I have no choice.}
"📬📬📬 ✋ ✌💣 👎 ❄ 💣✋ 👎" {… I am Determined.}
With that, Gaster broke the cap off the vial, and gulped down the liquid. The effect was immediate. His entire body felt like it was being ripped apart, atom by atom. Again. He started to melt even further as his non-melted eye socket gained a blazing red iris. He had no time to lose.
Gaster slammed a skeletal fist into the fractured timeline, pumping his magic into it, then through his body into the door. AS soon as he felt the connection form, he squeezed his sockets shut and bolted for the door, throwing it open and diving through.
