I Killed Our Parents?

"That bitch! I knew this was her plan! I just did not expect that she would win so easily... Oh, Lena... You even got a rare stone, how could you have done that!" Lexi leaned against the cubicle in the toilet and clenched her fist. Her veins popped and her manicured nails pierced into her skin, the slight pain caused her face to grimace. 

"Lena, Lena..." She mumbled and knocked on the ceramic sink. "Why do you find it so hard to understand that I hate it when you overshadow me? It's been so many years and you still find it difficult to remove yourself... You know that your twin is selfish so, can you just stop existing..." She uttered viciously. 

Suddenly, she heard a gasp behind her and turned around. She saw two people she was not expecting to see, Lena and Eloisa who had just entered the toilet also heard her words coincidentally.
