(i would like to think they were exchanging smiles not only because of keith cracking a joke to make lance feel better in that moment, but because they were also sharing an inside joke from the previous moment; keith being like: ah yes I remember back on our first day in the castle when you called me a dropout for correcting you, while lance was thinking: keith, that comeback is a bit late, you endearing little shit)
OKAY BUT THE FACT THAT WHEN HE SAYS “I LOVE YOU” HE LOOKS AWAY AND HE’S ALMOST SMILING.
LIKE HE KNOWS WHO HE’S SPEAKING TO IN PARTICULAR BUT STILL DOESN’T WANT TO SAY IT DIRECTLY.
AND THEN HE LOOKS UP AND HE ADDS “ALL OF YOU” WHICH IS THE TRUTH, BUT IT’S ALSO NOT WHAT HE REALLY MEANT.
I’m going to stab myself and it will be less painful.
