That's a non-issue with Darian, though, (for
SoA, anyhow). The most intense the relationship will get in
SoA is kissing, and only that towards the end, though Charname will certainly have somewhat more... provocative options. I'm asking in terms of responses to general flirts.
When you force-talk to Darian, you get four options: one for flirting with him, one for getting-to-know-you questions (many taken from the Ask Darian thread-I will give credit where it is due in the readme!), one for starting a more serious talk, and one to do nothing. For this example, Charname chooses the option to bring up the flirt menu.
From the menu of flirts, Charname chooses "(Try to catch Darian's gaze)". Darian then responds with "(Darian turns his eyes toward you-you have his attention)". Now from here, you can choose one of four or five variations on the "smile at him" theme, plus a more provocative response or two. All of the possible responses (aside from the special one or two) lead to the same "pool" of possible responses-I simply give Charname several options, depending on whether she wants to give him a mischeivous grin, easygoing smile, or simply blush at him. They all lead to the same pool of possible responses from him.
"The righteous need not cower before the drumbeat of human progress. Though the song of yesterday fades into the challenge of tomorrow, God still watches and judges us. Evil lurks in the datalinks as it lurked in the streets of yesterday, but it was never the streets that were evil." - Sister Miriam Godwinson, Sid Meier's Alpha Centauri
