I see this take all the time: that Capcom should've kept the detail from the original where 'Ada's gun was empty' in the Remake.
...That completely misses the point and ignores how totally different the context of the bridge scene is in the Original vs. the Remake.
Original Ada knew she was going to have to pull a gun on Leon to get the G-Virus from him. But she also knew she wouldn't be able to actually hurt him — so she emptied the gun beforehand. Ada knew she'd have to threaten him, but she also knew she couldn't follow through. It's a desperate move on her part, but there's no internal conflict happening during the confrontation itself. Ada already made her decision BEFORE the bridge scene. So when we see that her gun is empty, we realize she never wanted to hurt him, that she couldn't hurt him. Original Ada is more honest with herself about her feelings for Leon than Remake Ada is.
Remake Ada didn't know what was going to happen. Remake Ada sent Leon to get the G-Virus for her (something original Ada never did). She walks in thinking he'll just hand it over — that he still believes her FBI story. She's not prepared to have to threaten him. The bridge scene is where everything goes to broken for Remake Ada. She couldn't have 'emptied her gun because she didn't want to hurt Leon' — because she didn't even know she'd have to go there. But now Leon doesn't believe her anymore and won't hand over the G-Virus. So Ada has to make a choice: sacrifice Leon and complete the mission, or ditch the mission and spare him. Ada chooses Leon and refuses to shoot — even though she could have, even though she should have by mission logic.
"Ada's gun was empty' works brilliantly for Original, but it would make absolutely zero sense in Remake. Remake Ada couldn't have emptied her gun beforehand because she didn't know she'd need to threaten Leon — unlike original Ada. If Remake had done that, it would've looked like Ada didn't shoot Leon because she physically couldn't (empty clip), not because she chose not to.
Context is everything. A detail that worked perfectly for the original Leon/Ada dynamic is meaningless for the Remake versions, because their development and dynamic are completely different.
