"Another Knight of the Apocalypse huh?.." Lancelot muttered from next to Tristan, Lancelot's face blank and his hands in his pockets

"Hi! I'm Percival!" Percival ran up to you with a grin and eyes of interest

"It's nice to meet you.." Nasiens spoke up right after him, practically glued to Percival's hip

"Hmph.. They seem too weak to be a knight of the Apocalypse to me.." Gawain stated with her eyes closed but as soon as she opened she yelled "WOW! BEAUTIFUL!" Isolde and Anghalhad look at Gawain with confusion

"She looks nice.." Donny spoke up

"Where was she when we needed her.." Chion growled out clearly still hurt about Jade's death. Tristan grabbed his shoulder passing a stern look to silence him
