So if you've ever read my "Making a New Rule" story, you'll know I'm not the biggest fan of the hookup between Sara and Constantine for a lot of reasons. But I think the biggest reason was that I just found it was just unnecessary and a poor excuse just to say we hooked up a bisexual woman and bisexual man together on screen; thanks, Guggenheim. Objectively speaking, I guess I can see how the two would hookup only briefly considering their character traits but personally I just thought it was done in rather poor taste.
Sara Lance felt the change of mood in the air, as John Constantine was trying to comfort her and now apparently hitting on her. "Are you trying to seduce me, John?" Sara asked with a smirk as she tilted her head in amusement.
"Why? Would you have a problem that?" Constantine replied as he leaned in for a snog.
"Tempting." She started putting her finger in front of his lips. "But maybe later at another date ... then again I'm starting to outgrow meaningless sex." She said walking away from the warlock. "Also, I'm fairly certain you taste like an ashtray." She added with some sass.
"First the bloke from the other Earth, now the ex-assassin. I must be losing my touch." He said to himself with disappointment as he followed her.
Side Note: I do think that Sara's comment after Constantine left the Waverider was pretty funny.
