I didn't think it was a surprise to QA cause Tessa says (pg 344-346 in IH) "She said you'd get mad if you knew she came." Then she tells Adam & Gabby who she is by name and says she thinks Adam is pretty cause he's "all glowy & golden" . . . "Ah-veel says now he's just like you and me, Mommy."
I was thinking if QA didn't want them to know she was checking up on them she could've erased Tessa's memory of seeing her. To me, it's as if QA wanted them to know. (Knowing how well 4 yr olds can keep a secret) Does that make sense??
