You are correct that batman did reveal his identity to Carrie. In my 1st post i was mistaken. Went back and checked that panel after Carrie tracked him down.
Carrie was shown doing detective work and finding clues. Eg she found the key clue to joker.
She was also good with tech.
You keep moving the goalpost. presenting changes that happened decades after their debut as evidence. They aren't.
Tim become a great detective is irrelevant
Carrie's folks being stoners v Tim's absent parents is irrelevant since the point is they were both neglectful
Tim resisting adoption or length of time before moving into the manor.
All irrelevant since these aren't differences. It character development and shit that happened to the character as life took it's toll.
We are talking about the character's and their story when they debuted. The idea's and themes behind the construction of Carrie and Tim as presented to readers.
These include;
-The concept [Miller's new idea's and changes which made the new Robin different from what readers have come to expect/knew about Robin] -
the biggest and most important which is Miller's reworking of the Dynamic Duo's. batman rides in to rescue a kid who is in need then the kid later becomes robin.
Batman needs Robin [thank God Synder rectoned that in Rebirth]
Professional relationship rather than parental or guardian
-Themes present in their introduction [how, why they arrived at Robin and the factors in their home life] -
lived with parents who were neglectful leaving them unsupervised which is why they were able to get away with Robin duties for time without their parents awareness.
Both Save Batman pushing him to relent and train them [poor Damian, saving batman wasn't enough to 'earn' him the role]
-Character design and type [traits, skills, personality of the character] -
Unlike Dick and Jason, Carrie was constructed to be a representation of the era's Typical teens. Relateable. Insert characters not just Audience Surrogates.
She was a nerdy fan girl who liked doing typical teen stuff
So far you only have 1 valid difference and that is that tim saw robin do a move exclusive to the flying Grayson's. Tim being present when Mr and Mrs Garyson died no brainier it's Dick Grayson the solo survivor Grayson.
That's it everything else is you just reaching.
More important you choose to ignore or downplay the most remarkable themes that define Tim and his place in the pantheon of Robins is taken from Kelly. The change is the B&R.
Carrie was unique until Tim.
Carrie was and is Special
Before Carrie, Rob in was an orphan who was lost and in danger of going down a dark path who Bruce took in and provided parental support for.
Before Carrie Robin wasn't a mantle that was earned but was given because it was needed
Before Carrie Robin was an orphan and a regular kid not a disadvantaged kid
before Carrie robin was a kid with physical abilities [an acrobat or a street kid who was able to get the jump on Batman
Before Carrie Robin was Bruce's kid or Ward. Bruce had legal control
Before Carrie Batman saved Robins while Carrie saved batman
All these changes introduced by Miller during his redesign of Robin which were all present in Carrie and in her introduction were lifted and applied to Tim.
my goal here is not to convince you or anyone. The goal is to point out the many similarities and finally get it talked about.
To get people thinking about it and hopefully next time they revisit the DKR it'll jump out at them just like it did with me.
Respect? Respect is granting each Robin their place in the line up
Dick Grayson was the originator the Blue print for Robin. Carrie redefinded it for a generation of comi8c readers.
Her place in the pantheon of Robins is the 3rd Robin who redefined what and who Robin could be.
Edit
I can't be bothered typing more so I'll let a Tim fan@ the Drake Podcast counter for me with scans
http://thebatmanuniverse.net/tim-drake-2/
Tim lacked parental supervision.
Tim during his intro was good with tech and not very good at detective work
