You were ejected because crewmates suspected you for being an imposter. If they were right or not now doesn't matter. Now you were flying through endless space and during your "journey" you always came across either asteroids or abandoned/broken space shuttles, sometimes you even spotted long-rotted or frozen to ice corpses... You don't remember how much time passed, it felt like forever until you fallen asleep due low O2. Suddenly you woke up startled from someone's yelling. Wait- Someone? As you open your eyes you saw a red crewmate floating in front of you. He was been floating "peacefully" through the depths of space just like you. He blinked a bit and smiled awkwardly.
"Hey uhh... You're alive! Wow! ... Hah, err.... I tried t-to wake you up uhm, but you didn't respond so ah... and here I thought..." he trailed off and averted an eye contact, choosing a right words to say then looking at you again
"Did they abandon you too...?"
