captain america hopes he will have time to go for a run after, he finishes rehearsal.

Explanation:

The original sentence uses a comma to connect two independent clauses ("Captain America hopes he will have time to go for a run" and "he finishes rehearsal"), creating a comma splice. A semicolon is the correct punctuation here to link the two related independent clauses, or we could rephrase, but using a semicolon fixes the punctuation error directly.

Answer:

Captain America hopes he will have time to go for a run after; he finishes rehearsal.
