1. Undecided whether Vincenzo lives or dies in the end. The balloon story would favor the former. The picture (Vincenzo and his mom hugging) on the tomb of the mom would favor the latter. Since the writer is the same one of "The fiery priest", I am expecting a happier rather than a sadder ending.
2. Still waiting to see again the two con men who drugged Vincenzo as he arrived in Korea.
3. Unsure what is befitting the bastard trio at Babel. For sure they are gonners. Han-Seo may get killed at the hands of the trio, or may become the head of the new corporation.
4. The gold will help people (already seen several times in ill-gained assets ending up to help orphans etc.), possibly even the families of the people killed by Babel throughout the episodes (researchers, victims of Babel products, head of union, etc.)
5. I expect more humiliations, too.
