Um, did you by chance, catch the implication of this game? Canonically, the only thing of note is that, while Chris was escaping with Claire to safety, she fell asleep and had this nightmare. Don't trust the mistranslated dialogue. They're horrible. Steve calling Claire Sis is most likely a mistranslation, as he even called that big spider Sis. Claire never calls him Bro (This is in response to a comment by Alyson court that implies in CVX Claire took steve like a younger brother, showing him how to survive a boihazard, which NEVER HAPPENS in CVX, but only happens in DSC). Read one file called "monologue of Claire" with the fact in mind that Claire actually grew to have romantic feelings for Steve by the end of his life, and you'll see how depressing this game actually is. thanks for the cutscenes.
