Most (if not all) of the times Keith and Shiro say each others’ names

For @pastelvoodoo !!! Thank you for always making us happy♡
if you’re a sheith shipper and you want to think about the “i love you” line without also thinking about the “you’re my brother” line, that’s okay and ily. the brother line in no way should discourage you from shipping sheith, and it doesn’t devalue their relationship in any way, but it’s understandable if you feel uncomfortable about it for any reason, especially because it’s going to be considerable anti fodder until the s6 hype dies down.
if you’re a sheith shipper and you want to think about the “i love you” line in relation to the “you’re my brother” line, that’s also okay and ily too. the line is a testament to how close they are, and context matters. keith is telling shiro how much he values him in a moment where shiro is vulnerable and obviously not acting like himself. it’s objectively a beautiful moment. it’s the strongest and most explicit declaration of love in the entire series, and it’s even more powerful considering it comes from keith who tends to struggle with vocalizing his emotions.
at the end of the day, do whatever makes you the most comfortable, but keith loves shiro. that’s not up for debate in any way, shape, or form. it’s a good night for all of us sheith shippers thank you very much.
