I've Developed Two New Headcanons...
In order for V to earn the name, "Grumpy McTraumaBot" in Lizzy's phone, Lizzy would have to know V has trauma. So, my headcanon is that in the middle of the night or something V had a bit too much oil to drink or just had a bad day and starts venting to Lizzy over text and Lizzy gets booted out of sleepmode at like 2am because her phone is being blown up with just paragraph after paragraph of V's trauma and V is typing so fast it's riddled with horrendous grammatical, spelling, and punctuation errors which leads me into my next headcanon where V is super obsessive over having correct spelling, grammar, and punctuation in texts to the point where she does not make those mistakes ever. Unless she is venting.
