It was released as S02E11 on Hulu so it's not a special:

Special episodes are any episodes that did not originally air as part of a regular, usually numbered season. Sometimes a network will call an episode a "special" episode—as an example, "in this special holiday themed episode"—but still assign it a season and episode number; in those cases, it should not be added to the special season here but, instead, to the season assigned to it by the network.
