Nah, Haiden doesn't feel that way about Sal. Plus, Sal's four years older than him, so she probably sees him as a brat more than anything else. That's not to say that pretty boy's gonna get of easy, Haiden is very protective(and territorial) about those he cares about, so Michael will need to make sure not to give Haiden an excuse to plague him with a wave of viruses and hacks.

Edit: Also, I forgot to mention this earlier, but Haiden is actually kinda tall, being just an inch under six feet.
