'''First Meeting'''
{{quote|Greetings! I'm Demetrius, local scientist and father. Thanks for introducing yourself! I'm studying the local plants and animals from my home laboratory. Have you met my daughter Maru? She's interested to meet you.}}
'''Regular'''
{{quote|Maru helps me out in the lab sometimes... She's a good kid.}}
{{quote|This valley has a very vibrant and diverse ecosystem. That's one reason I was excited to move here.}}
{{quote|You're probably growing a lot of interesting plants on your farm, huh? Maybe I'll stop by your place some day and check it out.}}
{{quote|How's the farming business going? It's parsnip season, isn't it? I can imagine it being pretty peaceful, working outdoors with plants all day.}}
{{quote|Robin has a hot temper. It's better to stay on her good side. Don't tell her I said that.}}
{{quote|Let's see... If compounds in the rhizosphere contain sufficient levels of Carbon-13, then... Oh! Sorry. I was pondering some data and I didn't notice you there. Do you need anything?}}
{{quote|It's good to take a break from work every now and then. I guess that's kind of difficult when you live on a farm, though. Hey, at least in the winter you don't have to worry about crops.}}
''4+ Hearts''
{{quote|Robin has a hot temper. It's better to stay on her good side. ...now if I could only quantify her mood levels, perhaps I could model the fluctuations using a sinusoidal curve...}}
{{quote|Thanks for stopping by. I need to think about something other than legumes for a while. So, what have you been doing lately? That sounds interesting.}}
''6+ Hearts''
{{quote|Hi [Player]! How are you doing today? I wish I could make your farming job easier somehow.}}
{{quote|I became a scientist because I wanted to contribute to the progression of our species. Of course, none of this would be possible without farmers such as yourself.}}
{{quote|Hi [Player]. I'm always glad when you come for a visit. It's nice to have some company after all this lonely lab-work.}}
''If Player is married to Maru''
{{quote|It's hard to do good science without Maru's help... But her happiness is much more important than my experiment!}}
{{quote|I hope my daughter's keeping up on her math and science!}}
{{quote|I'm still flabbergasted about Maru's secret robot... was it all a dream?}}
'''Summer'''
{{quote|Sorry, I'm really busy. There's so many plants to study right now.}}
{{quote|Make sure to water your plants every day. Although, if you're using water retaining soil you don't need to worry about watering as often. It's pretty convenient.}}
{{quote|How's the farming business going? It's tomato season, isn't it? I can imagine it being pretty peaceful, working outdoors with plants all day.}}
{{quote|If you and Maru become friends, I'm sure she'll show you how to use that telescope out back. Pretty exciting, huh?}}
{{quote|Hmm... If strigolactone levels could be increased, would it have a proportional effect on mycorhizal growth? Oh! Sorry. I was pondering some data and I didn't notice you there. Do you need anything?}}
'''Fall'''
{{quote|During this time of year I divert my attentions to fungi.}}
{{quote|We know a lot about nature thanks to science. But there's always a lot more to learn.}}
{{quote|How's the farming business going? It's corn season, isn't it? I can imagine it being pretty peaceful, working outdoors with plants all day.}}
{{quote|Maru sure spends a lot of time working on those gadgets of hers. I'm glad she's so dedicated.}}
{{quote|Let's see... perhaps the nitrogen fixation level is affected by nematode secretions... Oh! Sorry. I was pondering some data and I didn't notice you there. Do you need anything?}}
'''Winter'''
{{quote|I'm taking a break from my research right now.}}
{{quote|Talk to my wife if you want to increase the size of your house.}}
{{quote|Do you have a kitchen in your house yet? Cooking is kind of like doing lab work.}}
{{quote|Do you have any animals on your farm?}}
{{quote|Let's see... if seasonal nitrogen levels could be modeled by a piecewise function... Oh! Sorry. I was analyzing data and I didn't notice you there. Do you need anything?}}
{{quote|Feel free to harvest as much lumber and stone from this area as you please.}}
