They'd been walking maybe ten more minutes when Yewon's hand shot up to her earpiece.
Jin stopped instantly, blade still low, watching her expression shift from blank focus into something sharper. The dripping water somewhere behind them seemed suddenly very loud in the silence that followed.
"Say that again," she said.
A pause. Jin could hear the faint, tinny edge of a voice on the other end but couldn't make out the words.
"Confirmed visual," Yewon repeated, half to herself, half to Jin. "You're certain."
Another pause, longer this time. Jin watched her jaw tighten, then ease, some decision settling behind her eyes.
"Good work," she said finally. "Hold position. We're coming to you."
She lowered her hand, already turning back the way they'd come.
