The next day after completing his mission and taking care of the fantastical animals Andrew is offered a raven by the store manager which he gladly accepted. The raven is very special. It is very prideful and can speak even more intelligent than other Ravens. The shop manager has a headache due to this as the raven will insult the customers and even make trouble for him.
But when Andrew appeared it didn't cause much trouble and even took the initiative to be with him around the shop and helping with other pet works. This made him dumbfounded then he decided give this to Andrew with this he can get rid of the raven and let Andrew also has a pet.
Andrew knew his celestial bird has limitations that isit can't be shown to the public easily and the celestial bird is constantly wandering in space. IT is immortal and can't die also has power to travel in space.
The celestial bird after signing a contract told him this while Andrew also agreed as he doesn't need to feed the celestial bird. The bird traverse through world and space gathering it's own food and travelling the new environments.
Now Andrew took the raven and goes to leaky couldron in a few days he is going to Hogwarts and the professor will arrive at any moment to guide him to buy things. He didn't want that but has no choce because Dumbledore has an eye on Andrew and rejecting a professor's guide will raise suspicion.
So he chose accept it. Today is the day the professor will arrive here. He is hoping that it won't be McGonagall as Andrew also didn't trust her. She is Dumbledore's spy and favours him. So he didn't want to be with McGonagall.
The door is knocked twice while Andrew opened it he saw a man with an expressionless face, black robes and a cape. This is Severus Snape. The moment Andrew saw Snape he breathed a sigh as Snape is much better to trust than McGonagall.
He may love Lily but the day Dumbledore done the life ritual on him he saw the disgust and a slight hatred for Dumbledore, James and Lily in snape's eyes. So he decided to ask Snape for helpnif there is any situation in future.
Snape looked at Andrew with complicated eyes, his eyes has emotions like pity, concern, regret and helplessness. He is there when Dumbledore done the ritual and heard the screams of Andrew when he felt the life force is forcibly stripping out of his body.
Snape then learned that Andrew became an obscurus, he felt pity for him and didn't do anything as Dumbledore set his eyes on Andrew. One wrong move and Dumbledore will squeeze the metal wire of dark wizard on his neck. So he stayed silent all these years.
He didn't have the love for Lily anymore when he saw what a bitch lily has become after tasting the fame.
She didn't even consider her child and kicked the pale Andrew out calling him a waste and saying ' he should be greatful to be of any use to them as a squib ', then he saw the hatred that is built in Andrew's eyes. That eyes are something that made him sleepless. They said a thousand words and each word has the same goal :
Kill, destroy and humiliate.
That eyes even frightened him, h asked Dumbledore to atleast take care of Andrew who is reaching his 3nd of life span soon but the answer he got changed his perspective on Dumbledore," some innocent lives will become hell to achieve a great purpose Severus. For the greater good we need to leave the things as they be ".
That answer not only shattered the good image of Dumbledore but also made him understand that since from the beginning everything that is done to Andrew is by Dumbledore and even the attack by voldemort on potter's is his plan.
This made Snape felt extreme disgust and grudge for Dumbledore. Doing cruel things to a newborn bay sealing his magic core and saying he is squib and then rob his life span then throwing a child into hell and he is calling it for the greater good what if Andrew developed into something much worse compared to voldemort, isn't one dark lord enough. Than Snape eyes widened, if Andrew is developed like this then what are things that are done to Tom riddle by Dumbledore at that time to turn him into that man. Snape shuddered at this and noted to help Andrew in secret.
