Ok, so he brought up SSR Bastet in response to me, because I was saying 'oh, the tough part here would be saving up jewels to try for Zhao Yun, then thunder Nyar, then SR Konohana Sakuya', which is another way of saying I need to hoard up jewels for 3 successive limited gacha sets.
SSR Bastet is then brought up, because the next limited set after new year's is the valentine's set, with SSR Bastet/fire Ame no Uzume/thunder Dike. It's a completely natural response to bring up.
