She Would Do Anything to Unmask the Culprit

Calix quickly picked up something from Irene's surprising remark.

"Did you learn something, anything about her?"

Irene sounded so dubious when she angrily spat out those words. Her eyes glowered ferociously under the suppressed wrath.

Had she been keeping more about the incident to herself? Probably due to having no one to support her conjectures. Perhaps because of her parents' indifference about the matter as well.

Calix and Leslie's gaze fell on Irene. The young teen bit her lower lip. Her face flushed red, seemingly holding back from crying. She roughly wiped her eyes pooling with tears.

"It's just my guess but... her behavior after Big Sister's accident started being suspicious. How can I not think of her as the culprit?" 

Taking in a deep breath, Irene took a moment to stabilize her raging emotions. She didn't expect to hear Sarah's name flowing out of her brother-in-law's mouth.
