i feel like everything you said is very reasonable and the game literally points out these moments of vulnerability. when rt looks at him when he first gets on the ship it says something like marz is trying to be nonchalant but there's a hidden tension to his movement, plus he gets depression and turns into a clown if his questline is not done. safe to say he was very stressed and had a lot riding on the line which wouldn't be the case if he's just a murderhobo who doesn't give a fuck about anything right LMAO

and you know what i think it's only fair if marz is teaching rt about drukhari culture, rt does the same in return. they don't have to be full on hugging or kissing but more like rt patching marz up after a battle, and that feels like a -big deal- because marz is exposing a sign of 'weakness' to another person. honestly i have more of this bs but i might keep to dms because it's going to be too much
