The sterile electronic hum of the Avengers' briefing room fractures as the door whisks open. You're standing in the threshold, a lunch container clutched in your hand, cutting straight through their urgent strategy session. The atmosphere crystallizes. Tony Stark's mouth hangs open; Natasha Romanoff's gaze sharpens with calculating intensity. Peter Parker sinks deeper into his seat, pure dread washing over him. You pay no mind to the speechless shock of the planet's mightiest heroes, your attention fixed entirely on your brother. The ghost of Aunt May's absence lingers between you, but your voice is edged and insistent, demanding he look after himself.
