[But only 'most likely' and 'I suppose'... don't think the fancy 'eh maybe' escapes her, Sebastian. Although after working and interacting with him enough, she just supposes that's how he is - not interpreting it as any kind of nihilistic mentality and more that Sebastian is just not used to extending his feelings, either by profession or upbringing (she has not completely ruled out that Sebastian might be on the special needs spectrum, tbh, because this is where her mind goes)]
[For now, though, she just gives a little shrug and a smile] It'll pass soon, at least. These things never last for too long before everything can go back to normal.
