Wes nodded. "Twice before this in fact," he said. "The first time I arrived was in the spring of 2014, several years after I died back home. I was here some time and then I was no longer here. I returned after a year and a half, but the dome sent me away again. I am a rare case, many who leave and return do not remember being here. Others may remember, but they aren't usually gone for years at a time before returning." Wes had intensive data on such matters. Especially given his own experience, it was interesting and pertinent work for him, and he devoted a lot of time and energy to researching the comings and goings of people in the dome.
