Narrative:
Instructing d-side on sea-I. Captain activated on a northbound 1200 code at 6500 ft with C650 wbound down from 90 for 40. R-side was busy handling overtake situation. I advise r-side he should stop the C650 above traffic and issue traffic. He started to quote traffic when approach called us on d-side. Approach advised if we had traffic; we said yes. After coming off the line I asked r-side does the C650 have the traffic. R-side says 'no.' I ask have you issued a traffic alert. He says 'no.' then he quotes traffic again with a traffic alert. The C650 advises he is climbing back up to 70. The C650 was never stopped or advised of altitude instruction.
