I've been looking through my grammar textbooks and checking examples online, but I'm still unsure about which of the following two examples is correct:
- Penso che ci sia qualcosa che non va.
- Penso che ci sia qualcosa che non vada.
More generally, if there are multiple verbs in a clause that requires the subjunctive, do all such verbs need to appear in the subjunctive or just the first?
