Meeting specific person at the end of the game

I know it's over a year late, but I figured I'd get on Arqade and answer some of these questions for the sake of completeness.

Obviously, spoilers ahead!

Since your link now points to an empty page, I'm not sure what answers you gave when talking to Sera. However, they're listed on the LIS Wiki. Essentially, there is a hidden convince counter keeping track of this which starts at 0. You have to get 5 or more points to convince her. Each 'correct' response during the conversation will increment the counter. Giving Sera the bracelet will add 3 to the counter. The guide even has a useful story flowchart for this scene which someone reverse-engineered from the files. You can use this to identify where the convince counter gets changed.

Using the following responses should give you a score of exactly 5, so you can convince her without needing the bracelet, but you must answer exactly as shown.

• Everybody's Broken
• I lost My Father
• Rachel Needs You
• I Thought My Dad Was Perfect
• Don't You Want To See Her?

(The guide also says you have to choose "She deserves to meet you" but the flowchart disproves this. Neither of the responses to that question has an effect. Some people also say you have to choose "You know my name" but that's not necessary either.)

Now, the interesting and crucial part was something I found when I was looking at the flowchart, which may have affected you. If you choose "Remember your letter?" the convince counter gets set to 2. Not incremented by 2, which is what I would have intuitively expected, but explicitly set to 2. If you were answering correctly up to this point, choosing this response makes your counter go down and then you will fail to convince her unless you give her the bracelet (2+3 points). Since many people will have probably seen the letter and chosen that option (and probably chose to kiss Rachel instead of take the bracelet), it's likely a lot of people didn't get to see Sera in the end cinematics due to this. Is it a bug? It's pretty debatable, since usually in LIS, optional choices unlocked by exploration are supposed to help you rather than hinder you.

I played the final chapter a few times on the latest version to test this.

• Using all 5 of the 'correct' answers. Rachel saw her mother.
• Using 4 of the 'correct' answers, but mentioning the letters. Rachel didn't see her mother, as expected.
• Using 4 of the 'correct' answers, but mentioning the letters, but then giving the bracelet. Rachel saw her mother.

Oh, and obviously, you must 'Tell Rachel the truth' in the finale after that. I hope that clears everything up!
