I would go with the consensus for the quote. If the episode has aired (give or take a few days), everything in the episode should be up for grabs. Nothing from season 1 should be considered a spoiler quote because it's a few years old. If someone hasn't watched the show and does consider it a spoiler, they enter at their own risk.

Technically, any quote for an episode someone hasn't seen is a spoiler. The episode title would be a spoiler to them. The whole page would be a spoiler. Everything can't be a spoiler especially when it's years old. A quote can't hurt because, even it can be seen out of context.
