Well, it can be really awkward. I'd say just act natural as much as you can after the initial apology. Don't make a big deal out of it by constantly bringing it up or acting strange around your friend. Maybe crack a small joke about it later, like 'Sorry about that earlier, hope I didn't blind you with my shocked face!', but only if you feel your friend is okay with that kind of humor.
Well, it can be a bit awkward. You could just smile and change the topic. You don't really need to get into details or pass judgment. Maybe say something like 'That's an interesting story, but let's talk about the cool places you visited instead.'

This is an extremely uncomfortable and awkward situation. First, try to keep it to yourself and not spread this private matter. It's important to respect their privacy.

First of all, it's important to approach this situation with respect and responsibility. If it was consensual, you should communicate openly with her about your feelings and expectations. You may also need to consider any potential consequences such as sexually transmitted diseases or pregnancy. It's advisable to get tested for STDs as soon as possible. And if there is a risk of pregnancy, be prepared to discuss options like contraception or support if she were to be pregnant.
You should immediately stop listening and try to forget what you heard. Pretend it never happened.
One way is to keep yourself busy. Engage in more activities during the vacation like exploring new places, trying new foods. The more occupied your mind is, the less you'll think about that scene.
