I’ve made some of these in the past, so here are some interaction ideas for Sigma.
ORISA
Sigma: “That melody… I can hear it again…”
Orisa: “I cannot detect the music you describe in the current vicinity. I shall ask Efi to test my sensors later.”
Orisa: “You appear to be distressed. Do you require my assistance?”
Sigma: “No… No. I shall be fine. I can hold it together.”
WINSTON
Sigma: “A giant gorilla? No, my mind must be playing tricks on me again…”
Winston: “I understand I can take a bit of getting used to.”
Winston: “Dr. Kuiper? Whatever happened to you after the incident on that space station?”
Sigma: “What happened? I… I don’t seem to recall… Curious…”.
DOOMFIST
Sigma: “Is this another opportunity for field research?”
Doomfist: “If that is what you wish to call it.”
Doomfist: “There is no need to worry, Dr. Kuiper. Your research is in good hands.”
Sigma: “I do hope my work will push humanity into a new, prosperous age.”
Doomfist: “Oh, it will.”
JUNKRAT
Sigma: “I can hear it! That melody, I can hear it again!”
Junkrat: “And here I thought I’d gone nuts.”
REAPER
Sigma: “I’ve been meaning to ask, are you a designer? That costume of yours is quite impressive.”
Reaper: “Something like that…”
SOMBRA
Sigma: “Your technological prowess is quite useful for my research, Sombra.”
Sombra: “I’m not the only one who’s being useful…”
Sombra: “Do you like puppets, Siebren?”
Sigma: “I’ve never been one for such things. Why do you ask?”
Sombra: Chuckles “No reason.”
WIDOWMAKER
Sigma: “You are the spitting image of a ballerina I once saw.”
Widowmaker: “You won’t be seeing her anymore.”
Widowmaker: “Another tool for Talon? Don’t get in my way.”
Sigma: “Talon? What are you talking about?”
BAPTISTE
Baptiste: “This is why I left Talon. I can’t let them continue abusing innocent people.”
Sigma: “They aid me with my research. They are not bad people.”
MOIRA
Sigma: “Ah! Dr. O’Deorain! Always a pleasure to conduct research with you.”
Moira: “Continued analysis of your mental state… No, Dr. Kuiper, the pleasure is all mine.”
Moira: “Tell me, Kuiper, what exactly is going on in that head of yours?”
Sigma: “Unfortunately, I’m not always sure myself…”
