Really good pit of despair for the character to sit in! I can't wait to see what kind of things begin to pull him out! (Unless this is a tragedy...) I would suggest standing in Corbin's shoes for a bit and figuring out how this could possibly change him; in fact, the very smallest ways (like if he avoids sitting in spots big enough for two or more, gets unnecessarily unnerved around alcohol, becomes defensive when he hears swear words) are the best ways to push a character and/or plot forward! Make the biggest list you can on how he could be affected by this experience, then add time to the equation and see how his future, less broken self would stand. Habits of avoiding couches and having prejudices against people who even have had a taste of alcohol will last the longest and leave the most realistic impression on your audience. ;)
