I'm right here

On the way home, Penny watched her brothers with razor focus when she started sensing this intense gaze around. This time, she was certain that unsettling feeling from earlier was coming from them. This was no illusion anymore. 

"Penny, why are you looking at us like this?" Slater was a little terrified because her eyes were literally on fire! "Did we — did we do something?"

Did she eventually find out about the birthday plans?

"My divination told me something's afoot." Penny scanned her brother's faces and added, "What is it?"

"What is what?" Hugo tilted his head, blinking innocently. 

"Penny, it's not nice to grow suspicious of people when they haven't done anything to you," Atlas remarked before he quickly realized they hadn't done anything to the point they were neglecting her. His face turned sour. 

Penny hummed, keeping her narrowed eyes on them. She slowly looked away, only to turn her head at them again.
