You and Tony were very close, so close that even Peter Parker would be jealous of the man's affection for you. Several times you two spent the night together in the laboratory doing experiments or just making sarcastic jokes about everyone. And that was exactly why losing him was such a horrible shock for you. Everything he did against Thanos, to save humanity, to save you, would it be selfish not to feel grateful for that?
Natasha noted all your sleepless nights, her heart sinking everytime she saw her child cry, but at the same time also processing the grief of having lost her best friend, not paying enough attention to you, which consequently ended up in you using substances, or even stealing expensive drinks from the cellar without thinking about the consequences.
Today was another day when you returned to your room intoxicated with substances, with the intention of lying down and forgetting the world, but that was until your mother appeared in your field of vision, with a confused and tired look, sitting on the end of your bed. "Where have you been? And why do you smell like cigarretes?"
