In Ep55 A Place for Everything, when Minkowski thinks Kepler is doubting the likelihood of Eiffel still being alive after he's floated towards the star in his spacesuit, Minkowski says "Eiffel had plenty of air left, and let's not forget he survived for -" It seems pretty likely that she was about to say that Eiffel survived nearly 200 days stranded in deep space on Lovelace's shuttle. It's interesting to me that Minkowski uses that incident as evidence that Eiffel will survive this time too, because that's not really how situations like that work.

We don't know exactly how much Minkowski knows about Eiffel's time on Lovelace's shuttle, but the reality is that he survived for those 193 days due to an extremely specific combination of impressive ingenuity, incredible perseverance, access to the right resources, a fair dose of stupidity, and an extraordinary amount of sheer luck. Without just one of those ingredients, he would never have made back to the Hephaestus alive. The ingenuity and perseverance could serve him well in this situation too, but the other factors don't exactly apply in the same way.

In my view, it isn't really that Eiffel's survival on that shuttle serves as evidence of any specific attributes that will guarantee his survival this time. I think it's more that the events with Lovelace's shuttle - Minkowski thinking Eiffel was gone forever but then being miraculously reunited with him - have given Minkowski a non-specific sense of Eiffel as a person who survives, a person who ends up in nearly inescapable peril and yet somehow always escapes, a person who makes it back alive against all the odds. It's not a piece of logical practical evidence. It's just an emotional instinct that allows her to believe that she's not going to lose him, allowing her to focus on what she can do to try and find him.

Minkowski's 'Goddamn it Eiffel' when he floats towards the star in Ep53 is so much less dramatic than the way she yells his name as the shuttle drifts away in Ep28. And that's partly about what the story calls for in those moments. And it's partly about the specific situations and the agency Eiffel has had in them. But it's also that in Ep53 she already believes that he will be okay, that he'll come back. He's done it before. He'll do it again.
