Mercy was floating around Pharah at the Temple of Anubis when she saw an artifact become uncovered. After successfully defending the objective she investigated the strange artifact. It was a wand, she figured it was in a pot that had been shattered during the mission—Junkrat always had a way of breaking and scattering objects all over the place. The wand was rather simple, it looked like it was carved from a short branch, it's fat end fit well in her palm, for some reason just holding this object made her feel powerful. The wand had the faintest of etchings that she would have scanned for Winston to analyze. Mercy decided to pocket her find and try to keep it for herself until she found out why it seemed so powerful.
It became difficult for Mercy to concentrate during the mission debriefing. "This mission would not have been a success without Angela's healing, I know combat medics tend to be overlooked, but our Angela always does a superb job!" Soldier said, regaining Mercy's attention. "Now that we have thwarted Talon's attempt to bypass Helix's security, we must plan our next move. Dismissed." The team began to disperse. Mercy was among the first to get up and start to leave.
"Angela?" Pharah tried to get Mercy's attention "You alright? You've been fidgeting a lot since we got back, it's worrying."
"Oh, I had a good idea towards the beginning of the debriefing," Mercy lied, though she didn't know why. "I want to get to my lab and start working on it right away." Mercy said, starting to rush past Pharah. Mercy continued rushing towards her lab, she was almost there, she made a turn into the final corridor of her journey only to bump into D.Va, sending both of them to the ground.
"Are you alright Ange?" D.Va asked, having recovered faster than Mercy. She was already on her feet and offering Mercy a hand.
"Oh, yes my dear, but a better question is: are you okay?"
"Never better!" D.Va responded with a bit of a bounce.
"Oh, the joys of youth," Mercy began to reminisce, "If only I were your age." She began to trail off, only to be brought back to current times by a warmth in her pocket, where she had stored the wand. She felt a wave of relief flow over her, she had began to shrink a little bit, her breasts firming up and shrinking a bit, her skin regained the little elasticity that had been lost to age, her muscles became more defined as they de-aged. She felt amazing, but what she was seeing invoked terror in her. She D.Va age rapidly she watched D.Va grow a few inches, her breasts became larger, then gained a little sag, some wrinkles appeared on her face, and her figure gained a little bit of pudge, as she almost doubled in age. Mercy swore she saw D.Va make painful faces during her transformation, but as quickly as the changes happened, her face took on a warm smile.
"Well I'm glad we're both okay." D.Va said, her voice had taken on a more adult tone, "I'll be on my way, I'm sure you've something great to work on, honey." She continued, before turning around and continuing on her way. As D.Va walked away she noticed that D.Va's suit was pulled really tight against her body, straining to hold the curves she had just gained—not all of which were good curves—and the legs of her suit were tight on her calves, Mercy couldn't let her walk away, could she? Mercy didn't know what to do...
