I didn't even realize I finished romancing Reyes. They really really dropped the ball on him. It felt like it was going well, things were progressing sufficiently romantically. But the end scene was practically just another flirt. There was no end point, and you barely even see or hear of him afterewards until the end scene after the main storyline, where it was just more casual flirting that was pretty low-key.
Huge disappointment and I regret selecting the hearts on him. I wish I did Jaal or Peebee, who have better than horrible scenes. (Peebee's is pretty okay, but clearly suffers as it's obviously re-used from the male Ryder and really stands out. Jaal's is scenic and at least shows nudity, but it's a bit short. Cora's is the only pretty good one but it's locked to male Ryder. But if it wasn't they'd just re-use the male scene anyway...)
Then again considering how decent male Ryder looked and how clownish default Sis Ryder is (With people on modding sites releasing saves of their better looking Ryders inspired by the same model / looks / theme of the default Sis Ryder) , they probably didn't put much thought/care to Sis Ryder in general.
