You can’t tell me that Blackwall doesn’t tease Sera about having a crush on the Inquisitor.
He’d catch her blushing while looking at Inky and go “You like her, don’t you?”
Sera would go “Stuff it!” and run away.
He’d give a small, knowing smile seeing Sera and Inky flirt during missions, because he knows that she reciprocates Sera’s feelings.
When Sera starts to has that nightmare about Inky dying, she goes to Blackwall about it, and Blackwall tells her “You’re in love with her” and Sera freaks out about it, but she knows it’s true.
Blackwall smiling when Sera giddily walks into the Tavern, sing-songing “She loves me back, she loves me back.”
During the years before Trespasser, she writes to Blackwall about how she’s planning to propose and asks for advice.
When Inky says yes, she runs up to Blackwall and screams “SHE SAID YES!” and Blackwall hugs her, because he’s so happy that she is.
