i quite agree! But how soon wull she find out, and will she be the first to know?
Luckily or we'd be in a very different situation I think it has to be pretty soon and she will be the first to know. The thing is irl you could never know how it all happened so it would be very hard to move on from it, like "oh she kissed you did she?" "you didn't lead her on like have dinner alone in our apartment?" "you stopped it as soon as it happened?" What you decide to believe and don't is up in the air.
Life would be very different for us! Probably, just a chance it could be leonard though? Or penny? Very tough, I bet they run into each other at work or something too, imagine that if her handbag still has that jar of money in it! Not that I think they would do the same joke twice
