 CONT: While on the beach, Doyle is twice seen wearing a wedding  ring. The first was brief, when Nadia confirmed that Phillip Bauer  had hacked into their system and he reached up to adjust his comm  unit in his left ear. But later, he again adjusted his comm unit  while she was lecturing him on not being authorized to recover Josh  before the component was back at CTU. That time, it was *very* clear  he was wearing it. Throughout the season, his left hand is clearly  visible without the ring. Presumably, this is Rick Schroders own  ring, and he forgot to take it off.
