I got to Asgore with 0 EXP and then I did the fight. I had the worn knife on me that I found as well as the heart locket. I did the fight and spared Asgore and of course Flowey killed him and then I battled Omega Flowey and I had to attack him as well. I spared him. I did not do the date with Papyrus or Alphys. What do I do?
