Grimlock ♥ Ultra Magnus

And Heimdall is underused in Marvel: he's a fascinating character they don't use all that often.   He's also more empathetic than I remember every time I see him.   It's the fact that he's never around that makes me forget, but there it is.   Every time. 

This is mostly told via a flashback, squished between the moments between Heimdall and Thor.   It's absolutely lovely seeing them talk, and I hope to see more of this, although I suspect that Heimdall will continue to be sorely underused in the future.
