He would later meet Laurel Lance and the two would fall in love. However, their relationship ended when he cheated on her with her sister.

In 2007, Oliver and Robert went on a fishing expedition together on the Gambit. During this expedition, the boat sank somewhere in the Pacific Ocean which killed Oliver and left Robert marooned on Lian Yu.

Robert Queen
Robert Queen would eventually return to Starling City and become the vigilante known as The Hood, driven by the grief of losing his son.

Laurel Lance

When encountering Earth-1's Oliver Queen, Laurel found it difficult to interact with him due to what Oliver meant to her. Earth-1's Oliver believed that Laurel could be redeemed after being told about her relationship with Oliver, which she eventually was.
