This is the first time we've seen him in weeks!
Wearing his usual baggy black t-shirt and baseball cap, Rob looked sullen — peering through the bushes and on the the ocean.
We don't know exactly what issues the 27-year-old has been battling, but on the latest episodes of Keeping Up With The Kardashians, it's all the family can talk about!
After Rob ditched the brood's Thailand trip, everyone expressed their concern for his well being.
We wish him the best, and hope he starts feeling like himself again! Heart you, Robby!
