Just within the context of the episode brainy not liking kelex made no sense to me. Apparently it's from the comic

Say what you will about how fast Nia's training is going but unlike with James at least they're showing the newest superhero training. 

I definitely agree with your third point. Kara knows James and Lena much better than Alex yet we don't see her having knowledge of the break up at all. When would Alex have even been told?

It's ridiculous is what it is

He cut off the snake head with a machete. No bat at all. I don't know how a machete got mistaken for a bat.

your stray thought: “CatCo got a redesign! I’d call it more of a lateral move than anything truly revolutionary.” i have to agree. the only thing they’re really doing is making catco what it should have been from the start

i’ve never been in prison but i definitely think they are supposed to check mail

I think it was a big mistake having Alex propose so fast 

It was mentioned at a dragon con panel that Sam became too popular to kill so they just kept her alive

Just remember this is the same show that wants us to buy James as guardian but they never show him training either 

It's been said this season won't have her in a romantic story. This is the only reason I think they're pushing brainy and Nia and not Kara and brainy

The season two Valentine's day episode also took place after the actual holiday. Alex becoming the director was supposed to limit her time in the field but that was forgotten very quickly

I feel exactly the same about Lena's isolation. 

It was shocking to see them think it was so necessary to remind of us Alex wanting kids at every opportunity as if we didn’t hear it the first time. This was essentially a forgotten plot by the writers this season or at the very least one they couldn’t fit in and now it’s like giving her a kid has some essential…

I can't say I agree with them have Lena make a decision like partnering with the military from such an emotionally vulnerable place. If anything it's a detriment to her character

I don't think the last time was quite a break up. It was their fight in the hallway after Thanksgiving dinner

It's my understanding that the original plan was to have Ruby be adopted by Alex but that was an Andrew kreisberg plan and when he was fired the show had to separate itself from him and his plot ideas
