Based on script, LongEr fell in love and married Shimin because of the prophesy that Shimin would be emperor. Why did Weizheng have to tell Jiancheng that he was leaving with Shimin causing unnecessary suspicion?
Weizheng knew the unscrupulous and evil nature of Liu Wenjing but did not warn Yanzhi to steer clear of him as he would use people at all costs to achieve his ends.
This drama made Zhangsun RongEr as a manipulative and cunning woman, although very smart, who schemed to ensure the protection of her husband's safety and continuity of Prince Qin household.
Why should Rouxi feel hurt with Jiancheng taking Hongxing as concubine when she didn't even love him. She had no right to demand Jianzheng's love and devotion when she didn't reciprocate and only have Shimin in her heart. Shimin so smart but couldn't figure this out?
Jiancheng won the battle this round with the revised battle plan from Weizheng, yet he couldn't even reflect that it was Weizheng who orchestrated all this. Rouxi could have reminded Jiancheng on this point. As if both Li Yuen and Jiancheng were dumb - Hongxian not even near the battleground, how could she have beheaded Liuheita? Problem lay with Rouxi refusing to give up on her love for Shimin but both brothers blamed each other instead of seeing her as the root cause for the brothers' tension, which Hongxian correctly pointed out.
Rouxi to be blamed for Jiancheng's unhappiness because of her coldness towards him so he found solace in Hongxian. If she were smart, she would scheme something to discredit/expose Hongxian.
The princess was so smart in the way she persuaded Jiancheng to mobilise the army but stupid in the previous episode when she didn't verify Haitang's story. Yanzhi also dumb, Weizheng already told her to be aware of HT and she saw HT's about face when WZ rejected her, yet YZ still showed sympathy to HT.
Weizheng so thorough, why no follow through to insist on answers from Hongxian? Instead he got diverted by her aaking to check on the assasin. No divorce papers, just serve it to his wife now.
Jianzheng was suspected of poisoning the knife so if he delivered the antidote, wouldn't Shiming's supporters argued that he indeed poisoned Shiming since he and nobody else had the antidote. Why didn't Yuanji tell Jianzheng that Hongxian was the one to save Rouxi when Yuanji was sent to assassinate her.
Yuanji was smart for once since he suspected that the previous enemy's subordinates poisoned the knife but Jiancheng overwhelmed by his suspicion against Shiming did not follow this line of thought.
If the fake son had not eaten a grain of rice for 2 days, wouldn't the mother had fed him before bringing him to Weizheng's house - Yantse couldn't detect the lie.
