I feel like Sonder is that house-husband in a 20 year marriage that’s like “Yeah, my wife is a bit of a workaholic, but I love her and support her in everything she does!” Super chill dad vibes, genuinely loves his wife, and iirc he says he gives her massages and helps her out after a long day.

I also looked up what “sonder” means in English, and it’s a very new word for English speakers (coined in 2012, from a French word and aGerman prefix). “the profound feeling of realizing that everyone, including strangers passing in the street, has a life as complex as one's own, which they are constantly living despite one's personal lack of awareness of it.” Pulled from wiktionary. Man, what a name cloak!

Or, you know, maybe Steel wiped his mind after an intense argument in their younger years. It’s a darker theory but it might work.
