DONT COUNT ESTI LMAO. she’s actually incredibly close to Thancred; they have an interesting rapport during ARR where she spends most of the time rolling her eyes at him, but they grow quite close after his return in HW. (The Emmanellain punch was a pivotal moment - sorry Emm u_u). He’s also the person she is most comfortable sharing her feelings and “personal woes” with. As far as most “distant”, it might be Krile. Old wounds from Eureka. (That said she really does love all of the Scions, so it’s a tough choice!).
