Shadow was depressed and sad over Angel gone,Sonic tried to get him in a good mood but he still sad,so he decided to take a nap,in his dream he was getting away with Angel,he is escaping from Black doom,he tried to save Angel but Black doom kill her,After the nightmare he scream with tears,the next day Pandora came and ask him what was wrong,he told her that his great friend Angel was dead because of Black doom.

Pandora:its ok shadow

Maria heard everything and remember that angel was her friend too,she came and give him a hug,they both had tears in their eyes,shadow apologized to Maria

Maria:is not your fault for losing her,losing someone you love is really hard,Snowdrop lost her family,Milky was sad over her and Pandora sad because she lost her best friend,what matter is that we got each other no matter what.

Shadow feel better so they have a family hug,and they have a family time,shadow is starting to get better,Sonic is glad that shadow is ok,but shadow still misses Angel,so Pandora sing to him: 

Ave Maria

Shadow was happy to have a sister like her,he feels better 💕

Shadow still has Angel's necklace that she gave him

Shadow saw a star in the sky so he made a wish

Shadow:for my  great friend,I wish that I can see Angel ones more

Shadow saw the star and he smiled for Angel,he went to the kitchen to have dinner that Snowdrop did
Shadow will always remember him and never forget her

The end
