This was great. Loved how Yugo and Alita served as foils to each other concerning naivety. Yugo was young and foolish when he joined in on Vector's black market, and years later he still could not wake up to the reality that the promise was never going to happen. He ended up just like his brother; an Icarus figure who let his dreams pull him out of a grounded life and suffered for it. Alita's amnesia has left her in a state of discovering (or perhaps rediscovering?) pubescent romance. Her naive "first love" style of romance lead her to do any and everything to keep up this young man's dream, and yet she can't accept the reality either. Her futile attempts to help him out in the long run just resulted in him breaking down and losing it.
A great tragedy that was short, simple, well executed, and effective. These replies on this thread (and on the previous chapters) are quite humorous to me. God forbid that a mangaka actually gives their characters notable flaws that tie into thematic writing.
