So I just finished this amazing show the other night. I can't stop thinking about it and mentally chewing on it. Definitely calls for a rewatch! I have since read a lot of the threads on this sub but I have a few random questions/observations I'd like to throw out there:

1. We learn from the characters that events in the loop can't be changed simply by a character traveling to a different time and doing things "differently," because they can't do things differently as evidenced by the fact that they didn't do things differently. That being the case, I found it strange that these same characters would at times seem so intent on "intervening" in history to ensure that events played out the way they were "supposed" to. An example that comes to mind is old Claudia sending Tronte to smother Regina so that Regina's death will motivate adult Claudia to be relentless in her efforts to prevent it. But as far as old Claudia knows, Regina succumbed to cancer in the bombed-out police station, and since that will "always happen," why would it even occur to her to send Tronte to make sure it happens? Relatedly, in the last episode, when old Adam confronts old Eva with the gun but doesn't shoot her, Eva immediately assumes that events are now unfolding differently than they always have, because she remembers that middle-aged Martha finds Eva shot to death in the study. But since middle-aged Martha would have no idea what exactly transpired between Adam and Eva, wouldn't she simply assume that the two had a longer conversation before Adam shoots her? Or that she shot herself? Or even that she had to pick up Adam's bullets off the floor so she could load the gun and shoot herself? The viewer knows (and Adam knows) that the loop is different this time, but why would Eva immediately assume that?
2. I watched the English dub rather than the original German with subtitles. I'll definitely watch the subbed version next time through. This is probably a question for u/mrbradleyp , but I'm curious about how aspects of the translation and recording process works. Specifically, I'm wondering to what extent "they" try to balance facilitating lip sync on the one hand, with natural and believable dialogue on the other hand. Several times I would hear a line and think to myself, "If this had been written in English, that line would have been...." I assume it was rendered the way it was in order to match the screen actor's lips as closely as possible. At times this resulted in almost comically awkward dialogue, such as in S03E08, when Tronte tells Claudia that he had always assumed Regina was his daughter, and Claudia replies, "For a long time I wished you were who the father had been." Also, with increasing frequency as the show progresses, one character will give another character a detailed explanation of something, and the other character will reply, "What are you saying?" Do the VO actors have any freedom to tweak the phrasing to make the dialogue more conversational, or are they stuck with the exact words as translated?
3. This isn't really a question, more an observation. One of the threads of the show is how and why Jonas could become Adam, and the viewer is meant to sympathize with teen Jonas when he repeatedly declares that he could never become Adam. I remember my own shock when Adam said explicitly that he believed the only means of salvation was annihilation of the entire world. In the loop, we get to see certain points in that decades-long transformation. But what really struck me is that Adam turned out to be right, and he was able to convince teen Jonas and me of that fact in almost an instant. The only way to "save" the origin world turned out to be the annihilation of both of the loop worlds, the only worlds Jonas and alt-Martha ever knew. I found it really thought provoking how quickly teen Jonas was willing to come around to that realization, especially since it was Adam explaining it to him, without having to go through the decades of additional pain and suffering that Adam had gone through. Along the same lines, it seemed to me that Adam was a much warmer and more sympathetic character in S03E08 than he had been in any previous episode. Maybe it's because he had finally learned the solution to the problem that had consumed his entire existence. In that sense, I think the two people who went through the tunnel of light and averted the car accident on the bridge were just as much Adam and Eva as they were Jonas and Martha.
