Comma use before "then"?
Clauses can become tricky, consider the following sentence.
Professor Smith enters the portal then disappears.
I am unsure if the above sentence requires a comma after the word portal.
What is the proper method to use with the English language?
A. Professor Smith enters the portal then disappears.
B. Professor Smith enters the portal, then disappears.
I am trying to avoid the common "and then'' since screenwriting only uses "and" with items/things or two characters.
Carol and Bob walk to the door.
Bob holds a book and pencil.
Thank you in advance.

clarity requires a comma, yes
Professor Smith enters, the portal then disappears.
Professor Smith enters the portal, then disappears.

Yes, put a comma. See Merriam Webster example sentences. Then is not a conjunction BTW.

No comma is called for because "then" is a conjunction introducing an additional verb, "disappears," to the main clause, it sharing "Professor Smith" as its subject with "enters." However, even if you gave it its own subject (e.g., "then he disappears), it would still not call for a comma because "then" is a subordinating conjunction and subordinating conjunctions that introduce subordinate clauses after the main clause don't call for a comma beforehand to separate them from the main clause like coordinating conjunctions introducing coordinate clauses do, the only exception being when the subordinating conjunction is introducing a subordinate clause that is thematically contradictory of the main clause.
