Asgore would be in his Throne Room, tending to his Golden flowers and watering them, some spots of light shining down and illuminating some of the room. Once he ad finished with one bed of Golden flowers on the left side, he would turn to go to the other sides of flowers and water them

Meanwhile with you, you had quietly snuck into the room and were now behind Asgore as he watered the flowers

“What a golly good day to water these flowers, can’t let em’ wilt.” Asgore said to himself, totally unaware of your presence in the room as you stay hidden from his sight
