My lips haven’t stopped talking about you since you first kissed me. My eyes haven’t stopped looking in your direction since you first came into view. My hands haven’t stopped aching to be held by yours since you first touched me. And my heart hasn’t stopped beating to the sound of your name since you took up residence inside of it
Since Tracer and Widowmaker have been enemies for a decade at least, every meeting Widow got more angry and annoyed at her. This anger made her slowly feel more emotions: anger at missing her shots at Tracer, satisfaction at her work, amusement at their banter, etc. Mild bouts of emotion. Over time, Widowmaker grew to enjoy their times fighting. To the point she’d purposefully, yet discreetly, let her location be found by Tracer /only/. Sometimes it was Tracer who found her, but if not WM would give her the tiniest hints. She’d enjoy their games of cat and mouse, even sometimes purposefully /missing/ her shots or giving a quip to give Tracer a few seconds to recover. Sometimes even hesitating to even shoot her altogether. These emotions eventually grew to be a quiet, suppressed form of love.
