Bliss' character was intentionably pliable, I think. Her interest at any given time was whatever her current boyfriend was interested in. That way she could be the spare Colby child that producers could fall back on, the understudy for multiple roles waiting in the wings. Claire Yarlett was already a potential starlet in the Aaron Spelling Productions stable, being groomed to move from main cast to lead role in a looming future series. She originated the role of Dakota Lane in Rituals before leaving for I don't know what reason, and next we saw her on TV on TC, which increased her visibility. Adrian Paul said words to the effect he'd been excited by the TC gig, had hopes for a longer run but shortly after being signed on was dismayed to hear that Claire's hours on TC were being reduced because she was filming elsewhere. Though Kolya appeared after Connie went on her world trip, AP recalled meeting her on set. Perhaps he was already filming his story earlier than we realise. Stops and starts and changes in direction in other stories likely caused by Stephie Beacham being re-signed at the last minute after her original 6-months gig was up & BS leaving earlier than planned, among other things + CY possibly being unable to reshoot her scenes may be why the Bliss-Kolya story felt separate and unintegrated with the other plots.
