Poor Lily looks so distraught even as she's paying unwavering attention to her big brother performing the surgery. His kind smile and relaxed mood are probably helping Lily just as much as his expertise is helping her bear. Lincoln sees this as an act of love and not at all a chore or bother. Now I'm not sure while the bear himself seems to indignant, but maybe he's annoyed at whatever caused him to be injured in the first place, or maybe Lincoln forgot the anesthetic. Either way, I'm sure all three will be happy soon. Thanks for the beautiful moment.
