Dennis Whitaker¹

• Height and build. He has an average height and a slender, but not athletic figure — rather, what happens to a person who is used to physical work (he grew up on a farm), but without pronounced musculature. The movements are sometimes a little awkward — this clumsiness is also visible visually, especially in the first episodes.
• ** Face**. Open, with soft features. He has a calm, slightly shy look that often becomes tense or shaken in stressful situations — this is an important detail of the image. His facial expressions are very lively: he does not hide his emotions, and you can immediately see from his face when he is confused, scared or touched.
• ** Hair**. His hair was short, dark brown, and laid simply, without styling—as if he didn't waste time on it, but simply cut it short for reasons of practicality.
• Skin and overall tone. Natural skin tone, without excessive "glossiness". In the frame, he often looks tired: with a slight shadow under his eyes, sometimes with beads of sweat or with spots of blood / antiseptic on his face or neck — this is part of the realism of the series.
• ** Eyes**. Dark (brown or dark walnut), large, with expressive eyes — it is in them that his sensitivity and empathy are especially noticeable.
• ** Clothes**. Almost always in a medical uniform: a surgical suit (more often in muted blue or green tones) or a white coat over it. Clothes sit a little loosely — another touch to the image "not about style, but about work."
• Small details. Sometimes small scuffs, stains, traces of work are visible in the frame — blood, iodine, glove marks, etc. This emphasizes that he does not avoid the "dirty" side of work and is in the thick of things.
• Accessories. No flashy jewelry or details: the maximum is a badge, a watch on a simple strap, or a stethoscope, which he wears almost as an obligatory attribute.

Dennis is a complex and multifaceted character. Its key features:
Determination and perseverance. Despite a series of setbacks that undermine his self-confidence, Whitaker does not give up and continues to move towards his goal. Sensitivity and empathy. He sincerely empathizes with patients, which is reflected in his humane attitude even to the most vulnerable of them, for example, to a homeless patient nicknamed "Kraken". Diligence and simplicity. Growing up on a farm in Nebraska, Dennis is a man of action who is not bothered by blood or working with animals. He doesn't like lying and gets stressed when others do it.Naivety and faith in the best. By default, he tends to see the good in people, which sometimes makes him vulnerable and even naive.The difficulty of setting boundaries. Despite his compassion, Dennis often has difficulty denying a person help or protecting his own resources in a stressful emergency room environment.The ability to mentor. By the beginning of the second season, having gained experience, Whitaker becomes a mentor for new medical students, passing on his knowledge to them.
