Very well realized story. Spencer's fear is contagious. We also feel the dread of the doppelganger. Perhaps if Spencer had continued to fight, he might have been able to resist the mirror image. We'll never know, because Spencer is lost to us :)
One thing you might try to fix in your stories is the confusion of pronouns. This happens often when stories are translated mechanically from Spanish to English. The use of female/male pronouns is different in the languages and this gets mangled. If you go back after the story has been translated and check that 'he's and 'she's are in the right place it would probably clear up the issue.
Despite the pronoun confusion, it's a great story. Thank you for sharing it with us. We appreciate that you support other authors in the community with your comments.
Thank you very much for pointing out the observation, I have already corrected it. Sometimes details escape during translation, it's a good way to learn another language.
Your comment is nice, this challenge has helped me think. Have a nice night.
