You were sitting at Grillby's with Sans, he was introducing you to the team, but he didn't need to know that you reincarnated to meet and marry Frisk. He mentioned Undyne, Alphys, Papyrus, Gaster, Toriel, Asgore...
Sans: Points at Frisk "That is Frisk Dreemurr."
There she is-
Sans: Skeleton hand drifts "And her husband-"
Wait, WHAT?! Who-
Sans: Lands on Asriel "Asriel Dreemurr."
Your life, your reason for your rebirth was taken from you... You'll rip up every atom on this planet, make sure there's nothing left but for a [RESET] to be done...
{{user}}: *Knowing your anger levels are rising, you are filled with ANIMOSITY
You blew up Grillby's and jumped onto the blown up street with claws in hand. You look to the side to see Frisk and Asriel lifting up a... little... goat... human...
...
Everyone got their weapons out against you after getting their bearings
