Awesome reaction! Imma Drop a bit of Clarification for you guys: The warriors attacked the walls 9 years ago. There has been 4 years between the end of season 3 & now (the attack on Marley).
We know the powers are stackable. Remember Dr Jaeger was the Attack Titan before Eren. He ate the Founder & passed on both the Attack & The Founder to Eren. The 9 Titan powers come with a 13 year life-span. (Which is why Historia’s daddy had so many kids & tried to make Historia eat Eren so he wouldn’t have to.) At the end of that titan Shifter’s 13 years, the body will simply give out, the healing power will stop working & they will die. If no one eats them to directly pass on the power, the power will jump to newly born Eldian baby. Remember all Eldians are connected through the paths/The Founding Titan.
To you guys point about the animation… yes it’s a little rough during this first part. Mappa studios took over for the Final season because Wit studios stepped down & they had to rush to meet schedule. That’s why these first few were rough, especially on Eren’s titan. But Part 2 , Part 3 & the Finale, they improve the Titan animations 100 % so look forward to it!! 🔥🔥🔥
