As much as I love these two and how happy they make each other, I'm genuinely worried that, between how durable he seems to be and how deep her S desires run, she's going to keep escalating more and more as he continues to match her until eventually she moves onto something that will end up genuinely damaging or potentially even lethal.
Granted, a punji pit is already pretty fucking lethal, but honestly that just lends credence to the whole escalation idea.
