It could have been done by switching the Cops and Zombies convention to a comic con convention with B5 and STVoy posters in the back ground.
ETA:
I really don't think I like how it looks like this series is ending.
Maybe Jane is suffering
PTSD from all the times she's been shot, or from the year long stalking / harassment from that drug Queen-pin Alice before Jane killed her this season and left over trauma from Hoyt's attentions in the 1st 2 seasons.
Maybe, but then
why runaway to Virginia, to work for an agency you've expressed only contempt for over the last 7 years, to a place with
out family, with
out friends. Jane, who is
totally grounded in her family, her friends, her work, even her church if earlier this season is to be believed... what is so bad in Boston that she plans to give it all up to be a flipping instructor for the FBI 483 (corrected after google search) miles away?
Like I said above, I'm glad Korsak finally called Maura on her "supportive" attitude towards Jane leaving this week and admitted his own misgivings.
I was also glad to see little brother Tommy and nephew TJ finally show up with plans to relocate to Boston, once more showing Jane
what she's going to miss when she leaves for Virginia, her family.
I can't see Jane being satisfied with such a passive job and if she wants one like that why not move to Boston's police academy as an instructor?
Yes, I know what you are probably going to say, "All god's children got to grow up someday." and maybe Jane needs to be isolated from her family and friends in order to do that...
... but I don't believe it.
Jane isn't a twentysomething who doesn't know what she wants out of life.
She's a grown up who's built more than a career in Boston, she's built a full life.
Ditching it all for a teaching position 7 states away makes even less sense than ditching it all to play General's wife to Casey 3 years ago.
