I would have been very happy about it - until this last episode with the future containing the bizarro nazi-wannabe Observers. Some have speculated that this future timeline will continue throughout the season, alternating between current and future episodes. Ugh.

This whole season has been setting up the future timeline, so yeah, it will continue. The casting sheet for Etta specified that the character would be recurring if the show continued into a fifth year.
