A/N Just my thoughts on what I think was going through Jemma's head in 1x06, enjoy
Jemma stood on the edge. Looking out seeing nothing but sky and sea rushing by. She knew she had to do it. She had to jump. If she died on the plane, it wouldn't just be her death, but the death of her closest friends. And she wasn't going to let that happen, she was going to save them, even if she couldn't save herself. She'd knocked Fitz out so that she'd have the chance to do it, for Pete's sake. So why couldn't she? Why couldn't she force herself to take the single step that would ensure the safety of her friends? She jerked as she once again tried to leap to her death. Then she heard it. The banging on glass and the sound of someone shouting her name. Fitz was struggling with the door that she'd locked, just in case he woke up. She saw the desperation on his face as he realized what she was going to do. She saw in that moment that Fitz would have done anything to save her. And seeing him, as distressed as he was, filled Jemma with an eerie feeling of calm. Looking into her best friend's eyes, she was able to find the bit of courage she needed. Not looking away from his face, Jemma stepped backwards, and was soon unaware of anything except the deafening wind and the memory of her best friend's face.
