Maybe *slightly* spoilery for Guardians of the Galaxy, but, seriously, by now I'm sure everyone has seen a pic of baby Groot by now. As for the other two... they're mostly just spoilery if you don't know that Chris Evans and Seb Stan are a couple of adorable dorks.
( Chris Evans, Seb Stan & baby Groot, together for the first time... )
