While Albert leaves the 118 in Season 5, he still comes back from time to time to support his brother. In Season 6, Episode 10, also known as the episode with Buck's near-death experience, Albert surprises Chimney with his mother and their father, Sang, from Korea. As we know, however, Chimney has a nearly nonexistent relationship with his father, who left Chimney and his mother behind in America.

In Season 6, Albert wants his half-brother and father to reconcile. He shares that Sang often asks about Chimney, Maddie (Jennifer Love Hewitt), and their daughter, Jee, and wants to have a relationship with his son and granddaughter. Although the episode is wrought with familial arguments, Chimney eventually starts to bridge the gap between himself and his father.

However, we haven't seen Albert since. Now that the promo for Season 6, Episode 16 is teasing that Chimney will finally propose to Maddie, we can't help but wonder if Albert will be there to support his future sister-in-law. Will Albert ever return to 9-1-1, or is he leaving for good?

As of April 25, the last 9-1-1 episode listed on his IMDb is Episode 11. But without a proper exit, we doubt Albert is gone for good.
