Twice in a Lifetime

Admiral Ozawa is seen in command of the USS California. She had previously commanded the USS Olympia. Both are Leviathan-class cruisers.

When Gordon takes Ed and Kelly home they seem surprised he's married to Laura yet in the Obituary it is stated that Gordon married Laura in 2019.

It's plausible that Ed and Kelly haven't read the whole obituary, because as high ranking officers of the Orville they are not expected to bother themselves with details. Furthermore, even if they have read the obituary, they may have simply forgotten this detail, and they didn't expect to see Gordon married because they hadn't aimed at retrieving him from the year 2025 (they expected to arrive in the year 2015). And lastly, their reaction may not be one of surprise due to finding out that he is married, but rather one of a shocking realization that bringing Gordon back is not going to be easy.

The originally streamed version of the episode contains what some consider a paradox (under certain time travel rules): Gordon's distress call says that he's been stranded in 2015 for 6 months, and when the final rescue takes place, LaMarr's report on their time jump says Gordon arrived "about a month ago". Both lines of audio (but not LaMarr's mouth) were later altered to avoid the possibility of paradox: the distress call says 3 months, and LaMarr says "four months ago".
