Felicity decided to stay put, waiting for Jennifer to bring Lucy in. "Don't want to risk missing something," the tomboy mumbled to herself. It didn't take long for her to hear the door open, two pairs of footsteps entering.
As the door closed, she heard the conversation start. "Alright, what's going on?" Lucy asked, in a tone ever-so-slightly different from usual. "Why did you drag me into the bathroom?" A question Felicity was curious about as well.
The girl in hiding heard a deep breath, shortly before Jennifer's response. "I... I've been having some... thoughts... about things, and... I think it's only right to let you know about it." Felicity could hear a lot of nervousness and uncertainty in her voice. "Not just because it's your sleepover, but... well, because it involves you."
Lucy's reaction was a confused, "Involves me? What's going on?" There was still that undertone of something Felicity couldn't quite place, before she heard Jennifer sit down on the tub, suddenly glad she picked the cabinet instead.
"There's, well... Since you showed us that Chronivac earlier, I've been having feelings, as if... as if I'm someone I'm not." Jennifer explained, Felicity making sure to listen close. "I know I'm Jennifer, I've always known myself as Jennifer, yet there's this part of me that's telling me I'm someone else. A part of me telling me I'm a boy." There was a brief pause, as Felicity pondered on that, before the other girl continued. "And... that part of me really doesn't want me to tell you, but it wouldn't be nice to keep it from you... especially since it's telling me you're my sister..."
"They're related...?" Felicity internally asked herself, wondering how that would work. "And Jennifer... feeling like she's a boy?" She was half tempted to just assume Jennifer was going to come out as trans, but decided to wait before jumping to conclusions, knowing she might still be missing something. Especially if it's related to whatever Jennifer said before.
After a few moments, she heard Lucy speak again. "You-" A short pause. "When we were scanning everyone into the Chronivac earlier, I saw that you and Felicity had profiles." That got Felicity's attention, wondering how her profile would be relevant, but before she could think on it, Lucy continued. "And when I slipped away for a 'bathroom' break a few minutes ago, I.. found the transformation active."
Things were starting to make sense, there being a transformation active explained what Jennifer said about turning back. "But how am I involved in that?" Felicity asked herself, before listening again as Lucy's pause ended.
"I was going to confront you and Felicity when it wore off, wanting to know why you would do that." Lucy paused again, confirming to Felicity that whatever transformation they're talking about, she's involved in. "But... Thank you for being honest... and... are you saying you didn't know either?"
There was a slight delay in Jennifer's response. "Sort of... I didn't at first, honest! I only knew my own life, not... not being your older brother." The 'older brother' detail changing a lot about what she just heard, but the next part was a much bigger bombshell. "And I still don't really know much... I just know Felicity either wanted to do it, or suggested we do it... and that it would've ended Sunday..."
