Background information Edit
Solok was played by actor Lou Wagner.
It was originally intended that the Ferengi who helped the team would be Quark (using his experience with the Cardassians during his time on Terok Nor), in a crossover with Star Trek: Deep Space Nine. However, this was changed when it was learned that Deep Space Nine would not air until several weeks after this episode. (Star Trek: The Next Generation Companion, p. 228)
Solok was originally named "Selok", but the name was previously used. Additionally, he wore no rank insignia on his collar or tattoo on his head, but was addressed as "DaiMon". (Star Trek: The Next Generation Companion, p. 229)
In the script, he was described as "very disreputable looking – even for a Ferengi. His clothes are rumpled and dirty... not a very successful Daimon in terms of money." Additionally, according to the pronunciation guide, his name was pronounced as "soh-LOK".
