SHIRO DIDNT REMEMBER MATT
Okay hear me out. He obviously remembered his best friend but like, how long had he gone without him after he sacrificed himself.
I mean when he met Pidge he didn’t think “Hey you look like someone I know” or when he saw the picture of Pidge and Matt he didn’t think “Wait I know them” SO DID HE FORGET WHAT MATT LOOKED LIKE. Guys what he was without him for so long he had forgotten what he looked like. What if he didn’t remember until Pidge said she was Sam’s daughter. He finally remembers how Matt looks. He can remember the terrified look on the boy when they were running from the craft, he remembers the worry marks on his sleeping face when he got knocked out.
Can you imagine after a long day he goes to Pidge’s room just to see her. And they just sit until he asks to see the picture of Matt. She shows it to him and he breathes a sigh of relief. When she asks why he is relieved he replies with tears in his eyes.
“I’d thought I’d forgotten what he looked like again.”
