From TVTropes, this might be the most sexually charged anipoke release.
Accidental Pervert: While seemingly innocent, if one pays attention to the perspective of the scene where Marina was speaking to Jimmy and Typhlosion, it can be deduced that Vincent had a clear view of Marina's butt for an extended period of time (this explains it

Butt-Monkey: When he's not being ignored by his crush Marina, Vincent is constantly embarrassing himself with his own fumbles. The instant Jimmy arrives in the hospital, Marina decides to hang up on Vincent; later, Vincent manages to cushion Marina's fall, but she doesn't notice because she's too busy making mutual eyes with Jimmy.
Crazy Jealous Guy: Vincent's not quite murderous towards Jimmy, but he's quite territorial about Marina—when confronted over the phone by his Unknown Rival, Jimmy is warned to steer clear of Vincent's "girlfriend" (which Marina is most certainly not).
Fanservice Pack: Marina's chest is given a bit of an upgrade compared to her in-game counterpart. One shot where Marina is getting a Poké Ball spends a good amount of time pointed at her chest.
Love Triangle: Jimmy carries a torch for Marina... and so does Vincent. Marina's affections, in turn, are clearly for Jimmy; Vincent is her dear friend, but she doesn't seem to see him as more than that. It's made even more obvious in the epilogue of the original version of the special (which is cut from the dub) where Marina gets Kenta's (Jimmy) phone number and gives him a call, and he's blushing and appears ecstatic.
Male Gaze: Marina, naturally, both in universe and to the audience. In the scene where Marina is talking to Vincent on the phone and then turns to greet Jimmy, Vincent has a lot of time to look at her butt. The audience gets a good amount of times to see her from behind too.
Ms. Fanservice: Marina may very well have the finest derriere out of all the main girl characters in the anime thus far.
