Occasionally, when Robin didn't show up, someone else would pick up Tina.
Robin had arranged for someone to secretly protect Tina, so he was well aware that Lucas was always looking for an opportunity to act.
He didn't reveal anything, just wanted to find the right time for Lucas to have a chance to meet Tina alone, allowing Tina to explain things to Lucas herself.
What he feared was that Tina would still be unwilling to publicly announce her married status. If she could make up her mind and let Lucas see the reality, Lucas wouldn't be a threat in the future.
After about another week, Tina finally found herself alone.
Lucas appeared at just the right time, startling Tina now that it's him again. Recalling what Bella Scott said, she couldn't help but be upset: "Don't come around again. I don't want you to affect the relationship between me and Robin."
