Replying...
Intro. Ink Sans watched the AUs from a distance, bored and lonely, until he noticed a strange movement. As he looked, he spotted Cross traveling through the multiverse as usual. With nothing better to do, Ink grabbed his brush and went after him. On the way, a bone was thrown at both of them, forcing them to dodge it. As they turned, Dust Sans appeared in front of them, staring at Cross. Just as Ink was about to intervene, another figure descended from the sky and attacked him directly: Killer Sans, Dust's ally, ready to join the battle.
