The rain hammered against the windows, mirroring the chaotic pounding in Ethan's chest. He felt as though the floor had given way beneath him. He stood rooted to the spot, the laptop screen reflecting his ashen face. He’d ordered the test on a whim, curious about some vague family stories. He'd never expected this.

He splashed water on his shirt, but didn't even notice, the damp patch a small detail in comparison to the earthquake of information he’d just received. He needed to *know*. He needed to understand. He started pacing, a frenetic energy coursing through him, the quiet apartment now feeling too small, too confining.
