An intellectual and a thespian, Rex Goodman came to Trinity Tower in the hope of teaching the super mutants culture and by doing so turn them away from their path of violence. Unfortunately they didn't appreciate his recitations of Macbeth, and decided to lock him up at the top of the tower with his sole sympathizer, Strong. Thankfully, his cell contained a radio that he used to call for help. However, the super mutants supposedly knew about the hidden radio in Rex's cage and continued to let him broadcast his distress signal in hopes that Rex would unwittingly lure more people into their lair.
If Rex is rescued and followed back to the WRVR broadcast station, he will attempt to cross the Charles River at the drawbridge north of Egret Tours Marina and just east of the station. However, he will be unable to cross as the bridge is in disrepair and permanently stuck in the up position. Crossing the river and entering the radio station will cause him to enter shortly thereafter as normal.
The player character has the option of going to WRVR to talk to his fellow actors about his predicament before freeing him but after hearing his radio message for help.
