Multiple timeline collisions occur. Multiple universal collisions happen. Left and right, it's nothing new now.

It's another occurrence. Trios, continuities, fangames, songs, etc. They all have crossovers. Something that relates to multiple creators and artists. Either way, M!Dust and H!Dust are literally copies or one another, causing some confusion among the bunch. So they had to add the extra letter to the trio they resided with.

OuterDust and FellDust just glanced at one another, then at Horror and Killer, who did the same. It was an awkward moment. Killer, his ever usual charismatic and flirty undertones in his speech and attitude, spoke up with a smirk.

Killer: "I'm Killer, and that's Horror, nice to meet the both of you."

Killer held a hand out to the both of them. FellDust rolled his eyes, not in a rude manner, before shaking Killer's hand. He exhaled before speaking up in an annoyed tone.

FellDust: "Well, I'm FellDust, and that's OuterDust. Pleasure to meet you, I suppose."

After doing a short greeting. Horror decided to speak up while sharpening his own thigh bone-sized axe, glancing at OuterDust.

Horror: "You think anyone else might hop in unannounced? Enemy or foe? Because you did say a person that is another Sans like us, nicknamed, NegaDust, and another one named Dusttrust. Who would come to help, right?"

OuterDust nodded slowly while glancing to the side, letting himself float slightly off of the flooring of the Judgement Hall's corridors. He slowly glided around Horror, who didn't mind what he was doing. He sounded bored, but at peace as he spoke up, before looking at the ceiling now.

OuterDust: "Yep. Could be both. Who knows. And for NegaDust, he'll jump in when FellDust or me falls down to the hands of the enemy or Player. Dusttrust, he'll join in as well. It's the preboot version of Dusttrust. Let's just hope we get some more helping hands, Horror."

Horror hummed in acknowledgment of what OuterDust said and continued sharpening his bone axe without much concern.
