It's not clear whether the two are interacting the whole time, or Tyler is just stalking her, as he did during one of season one's flashbacks. But there is some sort of conversation happening between the two.

"Day One. S2. Ready to make some magic," he wrote on Twitter.0comments
He then followed that up with an Instagram post captioned, "How do I get into character you ask? Well first I like to read the script, then I like to...who am I kidding? I just throw the jacket on, and #justlikethat Tony is back. #season2 #13reasonswhy #justasexcitedasyouare."
