"Well I haven't gone far travelling physically. My heart went to a good number of places though." She knew that probably would make zero sense, so odds are she might have to explain that quickly.

"When we were about to head off something happened and well...my heart ended up in my friends body, which sounds weird and is very hard to explain but it means that my body was comatose." Which considering she was awake now meant it went back eventually.

"After that I haven't been to that many worlds compared to my friends, but on the train means I get to do exactly that."
