Thanks for the input guys. I was going back and forth all week and ended up texting her Friday afternoon. Also i did decide to text that girl. I felt like I had gotten a good enough vibe that the risk wouldn't be too great. Figured the small risk of losing the freezeout was worth the potential benefits of giving her a small assignment during the trip.
She loves to do pickle-back shots so during my lunch break I specifically went to the supermarket and took a picture of a jar of pickles and texted her with the caption "want me to pick you up a jar?" The goal was some callback humor and making it seem spontaneous since it would seem like i just happened to be in the supermarket and thought of her. Exchange below (my comments in italics; also, while the whole convo was over the course of several hours, any consecutive texts were sent at the same time):
Me: Want me to pick you up a jar?
Her: Image didn't open

, but i'm assuming it's pickle juice??? If so, hellz yeaa!
Me: If that image really didn't open you are one of the finest guessers I have ever encountered haha. All packed up and ready to go?
Me: Or did you decide to cancel the trip and watch Olympic hockey all week
Her: Hahaha you got me Adam..
Her: I'll spend my week practicing the goal song
(at Madison Square Garden there's a song that's played everytime the Rangers score - I teased her for not singing along when we went)
Me: Judo too! Haha also one of my colleagues just gave me free tix to see phantom again this week so exciteddd
Me: But yes learn the goal song and let's def go to another win when you get back
(impossible since NHL is on three week break for Winter Olympics but figured it was a good way to make preliminary plans)
Me: Oh and don't bring knives on the plane - TSA is not going to like that
(when we were waiting in the security line at Madison Square Garden she joked that her bag was full of knives and guns)
Her: Haha, fine will leave the knives at home.. Sounds good, lets touch base when i get back. Have a fun week!
Me: You too! Get a nice tan and bring me back some souvenirs
Her: Will do
The whole point of the exchange was some callback humor and seeing if she'll actually follow through on bringing me back a souvenir. If she comes back with nothing but still wants to hang out, clearly I have some work to do. If she comes back with anything (i.e. keychain, t-shirt, etc) then I think it's a fairly big IOI and I can proceed with that knowledge.
