17 and 19 for Tracie and Preston?
17. Their ways of expressing their love.
Preston is less conveniently expressive since he keeps his cool but him opening up to Tracie, having fun with her doing Old World stuff, playing along her whole Disney story thing, going around old ruins to find items she likes and getting into all sorts of trouble with her is an expression of love in some way. However the one way he absolutely expresses that unconditional love towards her is that Preston is the only person that is patient with Tracie. Tracie has hard time understanding things and even harder time articulating a response when asked and sometimes these things can put her in danger and Preston understands her he knows she sees the things differently than most and he tries his best to actually listen to her because she isn’t stupid just people don’t understand what she is trying to say most of the time, she is just very hopeful and naive and absent minded and she doesn’t make sense if one doesn’t take the time to listen and Preston always does and that’s how she knows for sure that he loves her.
As for Tracie she usually collects pre-war things for him too, like books and magazines since unlike her he loves to read. She almost has the entire Silver Shroud series and she is working on getting all of them. She also put together a shelf in his Sanctuary house for him to display them on. And she often cooks his favorite food if she knows how to make it, accompanies him to Diamond City for a drink or noodles, learns to knit to make a better scarf than the one he has and other small acts of love and care. Also she is very physical so often she holds his hand, she massages his palm to help him relax when he has his PTSD dreams, strokes his hair and cuddles with him when he feels bad. And she knows when not to say a word and just be there for him if he needs her and really appreciates that because words for him are sometimes very hard but he still loves her support and loves that he has someone to lean on when he is at his worst and she was always there for him. And most importantly for a change Preston can be his more playful and cheerful self around her and even when he gets angry due to his depression she understands and she helps him through it so ultimately she really helps him pull himself up from that bad depressive episode and let his personality shine.
19. Describe how they communicate
Usually their communication is very silly, Tracie is silly she asks questions and Preston sometimes answers honestly sometimes he jokes about it. He understands what she is saying though, he is the only one that fully understands what she means, well first one the other people being Vicky and Gage much later but Gage is far older than her and Vicky is older too so he can’t really understand everything the way Preston does. She sometimes communicates non verbally and he picks up her cues then too, whether she wants them to do something stupid, something brave, mess around, prank MacCready or go and stargaze at the top of the Starlight Drive In. Their communication is simple but very meaningful and telling.
