300-600 words of dialogue (script isn't finalized). Sarah is the ex-girlfriend of a major character, Mark, who appears in flashbacks that give context about Mark and his past. (These aren't necessarily final names) They're both in their early-to-mid 20s. Months after the break-up, she has an unexpected encounter with him at a party when Mark shows up, drunk, and claims she texted him and asked him to get back together. She didn't actually do that, but Mark is experiencing delusions. Sarah awkwardly rebuffs him and makes it clear she’s moved on and is with someone else, but shows concern about his clearly deteriorating mental state.

She's kind of nerdy, intelligent and emotionally mature. She's a compassionate person generally. She’s a university student, hard working, and seems to have life pretty well figured out for someone in their 20s. At the same time, it's clear that she’s still somewhat hurt by how Mark's personal issues ruined their relationship and seeing him again is upsetting. However, her tone shows she still cares about him to some extent and is worried about him.
