See, She is still Waiting for You

When Sylvia entered Anais's room, she did not know she would see such a scene.

Her darling son was also present inside and was helping Anais cover herself with a blanket. But more importantly, she noticed a pretty recent bite mark on his neck.

(These two were flirting just a moment before and don't look like having any injuries, completely different from what Alice said…)

If Sylvia had been aware of the situation beforehand, she wouldn't have entered the room hastily without waiting a while after the knock. She only did so because her baby girl urgently asked for her help with Anais and didn't provide any other information.

Also, Alice was acting pretty strange as she had self-hypnotised herself into acting without emotions, which made Sylvia feel quite apprehensive, thinking that the dual cultivation had somehow backfired after some error.
