2- after rescuing Arsene - Allan reprimanded Euria for going after info about the black pebble when he told her to stop cause it was dangerous- anyway they find a cave that stores documents about the black pebbles- the birds who were following Arsene were caught and Kalian told them to tell chase that Kalian wishes he spares their lives ( actually chase told them to stop following Arsene and return to the nest but they disobeyed and currently Chase is in a killing spree to get rid of disobedient birds ). 

3- kalian and Plants study those documents about the black pebbles and kalian needs more info about the Arcus tempus since the Arcus in this timeline is incomplete he needs Chase to fill in the gap with memories of the complete Arcus - so Kalian gave plants a SILVER BRACELET- Kalian calls plants ( green messenger bird ) 😂😂 because plants receive/delivers messages to chase through the bird that infiltrated the royal guards - chase placed a bird kalian(Bern) is familiar with so that Kalian realizes that this bird is placed by Chase not Debullan - anyway the Bracelet reaches Chase and their master ( Bern&kyrie) sword master Taillan helped Chase with mana - so when Chase contacted Kalian - Kalian immediately went to the balcony and coverd his face and his shoulders shook then he told Chase that when everything is fine he wants them ( chase + Bern+ kyrie ) to climb the palace spire and have a drink 

also the part were Rea is shown to be unwanting to play engaged with Kalian is actually opposite in the novel- the rumors about them being engaged started when Kalian went missing ( when he was injured and went to Seigfried mannor ) and Rea held plants " hostage " so anyway she likes playing engaged cause it's a shield for those wanting to marry into Seigfried like who in their right mind would compete with the third prince 😂😂- and kalian uses the name of Seigfried- the king is also happy about such rumors-

Important events that got skipped 
Kalian sent Arsene to Gray to check whether Gray is still in cahoots with Randal - Euria ( head of the Arcane enclave ) accompanied him anyway alot happen and on their way back they get jumped by ( Zeon) those warriors of the great Dune and sense there were BIRDS following Arsene the birds reported to another bird that infiltrated the royal guards and that bird slipped the message to Plants and Plants informed Kalian 
so then Kalian knowing Arsene & Euria are in danger he immediately rode Raven to Arpeia Palace and Allan sensed it was Kalian outside so Allan left the office and then the king found out that Kalian escaped the royal palace 
anyway Kalian and Allan use the teleportation magic circle and go to rescue Arsene - when Kalian arrived Arsene was almost dead son Kalian saved Arsene and then a fight occurred where Kalian killed the warriors then he bandaged Arsene and placed him on Raven - Raven took off by itself to where the teleportation circle is - NoTe that Kalian was baffled by how he saved Arsene when Arsene was the one who killed him with an ice spear -- Anyway Plants escaped the palace and took Hina - they waited until Raven appeared carrying Arsene - and Plants was disgusted that he met Arsene - Note Plants & Arsene are on bad terms and always bickering 😂
