Hi and hello and welcome!! 👋 I'm Spoon! Really really PSYCHED that you're here! ^_^
I have two three kids! (One's fairly new so I forgot >.>)
First, and probably best connection to Cap, is Janet Van Dyne from AVAC! As soon as she can find a sewing machine (actually, I'm hoping she gets one as a gift next month!), she'll have Van Dyne's up and running again! She recently went on a shopping spree through the door with Sirius Black and brought back enough clothes for everyone! So she has spares if Steve needs any! ^_^ Other than that, she's got a crush on Cap, but she basically has a crush on everyone, so I'm sure they're pretty golden. Plus, she sided with him during Civil War!
Second is Kate Bishop from the comics. She just prays she won't embarrass herself in front of him or be a bit too sassy by pointing out (correct) opinions to him. So maybe these two can actually be friends! \o/
Last (and newest) is Rose Tyler from Doctor Who. She's going to be in a VERY good mood, because her Doctor is here and suddenly she's not so concerned about getting back home. Because the Doctor will find a way and she's gonna help. xD But she's very friendly and flirtatious, so...well, lemme just apologize to Steve right now for all my girls.
Jan will want to talk about Clark's awesome alien tech that he knows about, Kate will think he's pretty cool, and Rose will be majorly crushing and then wondering if hot aliens are her thing.
So...I would like all the lines! \o/ Can't wait to write with you!
