I honestly think that “I’m not going to forget where I had my first kiss with him” is going to be my favourite robron quote ever.
The casual way that Aaron acknowledges that from the very first moment he knew what he had with Robert was special. The fact that he makes out that it is so obvious that he would remember every detail of the kiss. Aaron has made it clear that this moment was unforgettable to him and he seems almost insulted that Liv could have suggested otherwise.
It’s not just the kiss that was significant; it’s the fact that it’s “with him”. And it’s not “where we had our first kiss” but it’s something that is exclusive to Aaron. It’s a simple line but it says so much about Aaron’s journey to loving Robert. This is Aaron taking ownership of the kiss, something given by Robert to him. It is Aaron acknowledging that he was gone on Robert the moment it happened because the kiss was so momentous, so earth-shattering, so life-changing.
We often say in this fandom that their first kiss is the moment that we decided that robron were extraordinary. It’s so amazing to have a character acknowledge that too.
