Since faun was beside him, he smiled and placed his hand on his because deku likes to touch hands :) and whatnot and he whispered to him.
"Hey, you should try being calmer, take your mind off ease."
"Kind-of, but I understand..Its okay to be nervous but you seem really worried...how about you think about it and do this for yourself not for anyone else..maybe you'll finally believe you deserve it.."
He smiled and rubbed his thumb gently against his hand, drawing small little imaginary circles on his hand with his thumb.
